Replacement verdict
Compatible functional replacement candidate
The AD5684RBRUZ and AD5686BRUZ-RL7 are both quad-channel, 16-bit nanoDAC+ voltage-output DACs from Analog Devices in the same 16-lead TSSOP package, sharing an SPI interface, internal 2.5 V reference, and 2.7 V to 5.5 V supply range. The AD5686BRUZ-RL7 offers a higher SPI clock rate and adds a RESET pin, so it can serve as a functional replacement for the AD5684RBRUZ in most designs, provided the system firmware accounts for the additional reset control and the higher serial clock capability. Designers should verify timing margins, reset pin handling, and reference configuration before committing to the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD5684RBRUZ | AD5686BRUZ-RL7 | Why it matters |
|---|---|---|---|
| Number of DAC Channels | 4 | 4 | Channel count determines how many independent analog outputs the device can drive in a system. |
| Resolution | 12 bits | 16 bits | Higher resolution provides finer output voltage steps, which is critical for precision control applications. |
| Integrated Reference | Yes, 2.5 V | No | An internal reference simplifies design and improves accuracy by eliminating the need for an external reference source. |
| Interface Type | SPI | SPI | The serial interface determines compatibility with the host microcontroller or FPGA. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | The supply range must match the system power rails for proper operation. |
| Output Voltage Range | 0 V to VREF | 0 V to VREF | Defines the usable analog output span, which must align with the target application requirements. |
| Package Type | TSSOP-16 | TSSOP-16 | Package type affects PCB footprint, thermal performance, and assembly compatibility. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +105°C | The temperature range ensures reliable operation in the intended environment. |
| INL (Integral Nonlinearity) | ±1 LSB | ±4 LSB | INL indicates the maximum deviation from an ideal transfer function, directly impacting accuracy. |
| Power Consumption | 2.5 mW at 3 V | 3.5 mW at 3 V | Power consumption is critical for portable and low-power embedded designs. |
