LTC2051IMS8#PBF

LTC2051 is a dual zero-drift operational amplifier. The current consumption is 750μA per op amp. The LTC2051, despite its miniature size, feature uncompromising DC performance. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and common mode rejection ratio (CMRR) of more than 130dB. The input common mode voltage ranges from the negative supply up to typically 1V from the positive supply. The LTC2051 also has an enhanced output stage capable of driving loads as low as 2Kohm to both supply rails. Application includes thermocouple amplifiers, electronic scales, medical instrumentation, strain gauge amplifiers, high resolution data acquisition, DC accurate RC active filters and low side current sense.
