Replacement verdict
Not a drop-in replacement
The AD5410AREZ and AD5415YRU are not functionally interchangeable. The AD5410AREZ is a single-channel 12-bit 4-20 mA current-loop DAC with HART connectivity, while the AD5415YRU is a dual-channel 12-bit multiplying DAC with current output. They differ in output type, channel count, digital interface, and package footprint, requiring complete circuit redesign for substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD5410AREZ | AD5415YRU | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Determines the smallest analog output step; matching resolution ensures comparable output granularity. |
| Number of DAC Channels | 1 | 2 | Channel count dictates how many independent analog outputs are available, affecting system architecture and board space. |
| Output Type | Current (4 mA to 20 mA) | Voltage (unbuffered/voltage output) | Current-loop versus voltage output determines the interface type and whether external conversion circuitry is needed. |
| Interface | SPI | SPI | Digital interface compatibility affects how easily the device connects to host controllers and existing firmware. |
| Supply Voltage | 10.8 V to 40 V (AVDD) | 2.5 V to 5.5 V | Supply range determines power architecture compatibility and whether level shifting or additional rails are required. |
| Operating Temperature Range | -40 °C to +105 °C | -40 °C to +125 °C | Temperature range affects suitability for industrial, automotive, or harsh-environment applications. |
| Package / Mounting | 24-Lead TSSOP (RE-24) | 16-Lead TSSOP (RU-16) | Package footprint and pin count impact PCB layout, thermal performance, and drop-in substitutability. |

Frequently asked questions
What are the primary functional differences between the AD5410AREZ and the AD5415YRU?
The AD5410AREZ is a single-channel, 12-bit current-source digital-to-analog converter (DAC) designed for industrial process control, providing a 4 mA to 20 mA output. The AD5415YRU is a dual-channel, 12-bit multiplying DAC with a current output, requiring an external op-amp for voltage output. They serve different signal-chain roles: the AD5410 integrates the current-drive circuitry, while the AD5415 provides a raw multiplying DAC core.
Are the AD5410AREZ and AD5415YRU pin-compatible or package-compatible?
No. The AD5410AREZ is supplied in a 24-lead TSSOP (RE-24-1) package, while the AD5415YRU is supplied in a 24-lead TSSOP (RU-24) package. Although both use a 24-lead TSSOP outline, their pin functions and internal architectures differ, so they are not pin-to-pin replacements.
Can the AD5410AREZ and AD5415YRU operate from the same supply voltage?
No. The AD5410AREZ requires an analog supply (AVDD) of 10.8 V to 40 V and a digital supply (DVDD) of 2.7 V to 5.5 V. The AD5415YRU operates from a single 2.5 V to 5.5 V supply (VDD) and a reference input. Their supply requirements and voltage ranges are not interchangeable.
Which device is better suited for 4 mA to 20 mA industrial current-loop applications?
The AD5410AREZ is specifically designed for 4 mA to 20 mA current-loop applications, integrating the current output stage and compliance circuitry. The AD5415YRU is a multiplying DAC with a current output and does not natively provide a 4 mA to 20 mA loop drive without additional external signal conditioning.
Do the AD5410AREZ and AD5415YRU have the same digital interface?
No. The AD5410AREZ uses a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The AD5415YRU uses a parallel interface with 12 data bits plus control lines. The interface type, timing, and control registers are different and not directly interchangeable.
What is the resolution and accuracy specification for each device?
Both devices are 12-bit DACs. The AD5410AREZ offers 12-bit resolution with integral nonlinearity (INL) of ±0.024% FSR maximum and total unadjusted error (TUE) of ±0.1% FSR maximum at 25°C. The AD5415YRU offers 12-bit resolution with relative accuracy (INL) of ±1 LSB maximum and differential nonlinearity (DNL) of ±1 LSB maximum. Accuracy should be evaluated per the respective datasheet conditions.
Can the AD5415YRU directly replace the AD5410AREZ in an existing 4 mA to 20 mA design?
No. The AD5415YRU lacks the integrated current-output amplifier and 4 mA to 20 mA output range of the AD5410AREZ. A direct replacement would require additional external circuitry, different supply rails, and a different digital interface, making it unsuitable as a drop-in substitute.
What are the operating temperature ranges for the AD5410AREZ and AD5415YRU?
The AD5410AREZ is specified for the industrial temperature range of −40°C to +105°C. The AD5415YRU is specified for the automotive temperature range of −40°C to +125°C. Designers should verify the exact grade suffix and datasheet conditions for the intended application.
