Maxim Alternatives for the National Semiconductor LM4666
National Semiconductor LM4666
Benefits of the MAX9701 over the LM4666:
Lower THD (0.08% vs. 0.65%), higher PSRR (72dB vs. 60dB), higher CMRR (66dB vs. 48dB) and lower supply current (8mA over temp vs. 10mA @ 25°C) than the LM4666
Four pin-selectable gains vs. one for LM4666
Lower offset voltage (30mV over temp vs. 35mV @ 25°C)
Specified switching frequencies and external synchronization
The LM4666 is unspecified for switching frequency
Benefits of the LM4666 over the MAX9701:
LM4666 is in smaller 3mm x 4mm LLP (TDFN) vs. 4mm x 4mm TQFN
LM4666 has higher input impedance
