ADI LTC2055HVCMS8#TRPBF

The LTC2054/LTC2055 are low power, low noise, single/ dual, zero- drift operational amplifiers with an extended temperature version (LTC2054MP) that has guaranteed specifications from - 55°C to 150°C. They are available in TSOT- 23 (ThinSOTm) and MS8 packages. For space limited applications, the LTC2055 is also available in a 3mm×3mm×0.8mm dual fine pitch leadless package (DFN). They operate from a single 2.7V minimum supply and support ±5V applications. The current consumption is typically 150μA for the LTC2054 and 130μA / amp for the LTC2055. The LTC2054/LTC2055, despite their miniature size, feature uncompromising DC performance. The maximum input offset voltage and offset drift are 3.0μV and 30nV / °C over the - 40°C to 85°C industrial temperature range. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and common mode rejection ratio (CMRR) of 130dB (typ). The input common mode voltage ranges from the negative supply up to typically 0.5V below the positive supply. The open- loop gain is typically 140dB. The LTC2054/LTC2055 also feature a 1.6μVP - P DC to 10Hz noise and a 500kHz gain- bandwidth product.
