Replacement verdict
Compatible functional replacement candidate
The ADS8341EB/2K5G4 is a tape-and-reel variant of the ADS8341E and shares the same 16-bit SAR ADC core, 4-channel multiplexer, SPI interface, and SSOP-16 package, making it a functionally compatible replacement candidate. The only meaningful distinction is the packaging format, which requires validation against the assembly process rather than the electrical design.

Key electrical and mechanical differences between the two devices
| Parameter | ADS8341E | ADS8341EB/2K5G4 | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Determines the smallest analog signal change the ADC can resolve; identical resolution means equivalent measurement precision. |
| Number of Input Channels | 4 single-ended / 2 differential | 4 single-ended / 2 differential | Defines how many analog signals can be measured; matching channel configuration allows direct functional substitution. |
| Sampling Rate | 100 kSPS | 100 kSPS | Sets the maximum conversion throughput; identical rates ensure the same signal bandwidth can be captured. |
| Supply Voltage | 2.7 V to 5.25 V | 2.7 V to 5.25 V | Determines system compatibility and interface logic levels; matching range allows use in the same power domain. |
| Interface Type | SPI-compatible serial | SPI-compatible serial | Defines the digital communication protocol; identical interface ensures drop-in compatibility with the host controller. |
| Package / Mounting | 16-SSOP (surface mount) | 16-SSOP (surface mount) | Affects PCB footprint and assembly; matching package allows the same board layout to be used. |
| Packaging / Ordering Format | Tube / individual | Tape & Reel (2000 units) | Impacts manufacturing handling and inventory; reel packaging suits automated high-volume assembly while tube suits prototyping. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Defines the environmental envelope for reliable operation; matching ranges ensure equivalent application suitability. |

Frequently asked questions
What are the key differences between the ADS8341E and the ADS8341EB/2K5G4?
Both devices are 16-bit, 4-channel, serial-output successive-approximation ADCs from Texas Instruments in a 16-pin SSOP (DBQ) package. The ADS8341E is supplied in tube/rail packaging, while the ADS8341EB/2K5G4 is the same converter delivered in tape-and-reel packaging (2,500 units per reel) with a green/RoHS-compliant material set. The electrical core specifications are identical; the suffix differences denote packaging and environmental compliance rather than converter performance.
Are the ADS8341E and ADS8341EB/2K5G4 electrically and functionally interchangeable?
Yes. Both parts share the same 16-bit SAR architecture, 4 single-ended or 2 differential input channels, SPI-compatible serial interface, and 2.7 V to 5.25 V supply range. Because the die and pinout are the same, they are functionally interchangeable in a given design; the only practical difference is the delivery format (rails vs. tape-and-reel) and the green-material designation on the EB/2K5G4 ordering code.
What is the resolution and sampling rate of these ADCs?
Both the ADS8341E and ADS8341EB/2K5G4 are 16-bit successive-approximation ADCs with a maximum throughput of 100 kSPS. They provide no missing codes to 16 bits and support single-ended (4-channel) or differential (2-channel) input configurations.
What supply voltage and reference requirements apply to both parts?
Both devices operate from a single analog supply of 2.7 V to 5.25 V and a digital supply of 2.7 V to 5.25 V. An external reference voltage (VREF) is required and must be applied between the REF+ and REF- pins; the reference sets the full-scale input range. The devices do not include an internal reference, so the reference source must be provided externally in the design.
What package and pin configuration do these devices use?
Both the ADS8341E and ADS8341EB/2K5G4 are offered in a 16-pin SSOP (Shrink Small Outline Package, DBQ suffix) with a 0.635 mm pitch. The pinout includes four analog input channels (CH0–CH3), reference inputs (REF+ and REF-), supply and ground pins, and the serial interface signals (CS, DIN, DOUT, DCLK, BUSY). The package and pinout are identical between the two ordering codes.
What is the difference between the "E" and "EB/2K5G4" ordering suffixes?
The "E" suffix in ADS8341E denotes the standard device in a 16-pin SSOP package supplied in tube/rail form. The "EB/2K5G4" suffix denotes the same converter in tape-and-reel packaging (2,500 units per reel, indicated by "2K5") with a "G4" green-material/RoHS-compliant finish. The "B" in the EB code reflects the tape-and-reel packaging variant. Neither suffix changes the converter's electrical specifications.
What serial interface do these ADCs use, and how do they connect to a host processor?
Both parts use a 4-wire SPI-compatible serial interface consisting of CS (chip select), DIN (data in), DOUT (data out), and DCLK (serial clock), plus a BUSY output that indicates conversion completion. The interface is compatible with most microcontrollers and DSPs, and the devices can be daisy-chained or operated with a dedicated chip select per device. The interface timing and protocol are identical between the ADS8341E and ADS8341EB/2K5G4.
Which part should be selected for automated SMT production lines?
The ADS8341EB/2K5G4 is the appropriate choice for high-volume automated surface-mount assembly because it is supplied in tape-and-reel (2,500 units per reel), which is compatible with pick-and-place feeders. The ADS8341E in tube/rail packaging is better suited to low-volume prototyping or manual assembly. Both share the same 16-pin SSOP footprint, so the PCB land pattern does not change between them.
