Replacement verdict
Compatible functional replacement candidate
The AD7790BRMZ and AD7791BRM are both single-channel, 24-bit sigma-delta ADCs from Analog Devices in the same 10-lead MSOP package, sharing a closely related core architecture and SPI interface. The AD7791BRM offers a higher output data rate and a buffered differential input, making it a viable functional substitute for the AD7790BRM in many low-power precision measurement designs, provided the system can accommodate the differences in output data rate, input configuration, and supply range. Designers should validate these parameters against their specific application requirements before committing to the replacement.
