LT1991 Individual Battery Cell Monitor for a 4-Cell Battery

Aug 2nd 2004
High input impedance of LT1991 P3 and M3 inputs, ( 150K ), is used to eliminate errors introduced by the analog switch resistance which is very low compared to LT1991 input resistance. The MSB signal is used to change the common mode voltage when reading the cells on the battery stack. ...

LTC2057 Differential Thermocouple Amplifier

Dec 9th 2003
The LTC2057 is a high voltage, low noise, zero-drift operational amplifier that offers precision DC performance over a wide supply range of 4.75V to 36V or 4.75V to 60V for the LTC2057HV. Offset voltage and 1/f noise are suppressed, allowing this amplifier to achieve a maximum offset voltage of 4μV and a DC to 10Hz input ...
