The LTC2051/LTC2052, despite their miniature size, feature uncompromising DC performance. The typical input offset voltage and offset drift are 0.5V and 10nV/C. 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/LTC2052 also have an enhanced output stage capable of driving loads as low as 2k to both supply rails. The open-loop gain is typically 140dB. The LTC2051/ LTC2052 also feature a 1.5VP-P DC to 10Hz noise and a 3MHz gain-bandwidth product.
