Speed: The MAX1393/96 operates up to 300ksps vs. 200ksps max. for the Analog Devices AD7466
0.9V to VDD External Reference Input Pin: Maxim's part allows an external reference input for increased flexibility. The Analog Devices AD7466 only allows a ratiometric measurement with VDD supply as the reference.
Improved Accuracy: MAX1393, MAX1396 claims a guaranteed ±1 LSB INL, ±1 LSB DNL and ±2 LSB TUE vs. the Analog Devices AD7466's 1.5LSB INL, and -0.9 to +1.5 LSB DNL specifications.
Lower Power 3V operation: The MAX1393/96 achieves 0.53mW typ. The Analog Devices AD7466 uses 0.62mW at 100ksps.
Benefits of the AD7466
over the MAX1393, MAX1396:
Lower power at 1.6V operation: 0.12mW for the Analog Devices AD7466 vs. Maxim's 0.28mW, 100ksps
