LTC2055CDD#PBF

LTC2055 is low power, low noise, zero-drift operational amplifier. This 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 130dB (typ). Typical applications are thermocouple amplifiers, electronic scales, medical instrumentation, strain gauge amplifiers, high resolution data acquisition, DC accurate RC active filters, low side current sense, battery-powered systems.

• Supply current is 175µA maximum (TA = 25°C, no load) and (VS = 3V, 5V)
• Input offset voltage is ±3µV at TA = 25°C, VS = 3V, 5V
• Output swings rail-to-rail
• Large-signal voltage gain is 140dB (RL = 100k, VS = 5V, VOUT = VS/2) and (TA = 25°C. VS = 3V, 5V)
• Common mode rejection ratio (VCM = GND to V+ - 0.7V) and (TA = 25°C, VS = 3V/5V) is 130dB
• Power supply rejection ratio (VS = 2.7V to 6V) and (TA = 25°C, VS = 3V/5V) is 130dB
• Input bias current is ±1pA typical at TA = 25°C, VS = 3V, 5V
• Supply operation is 2.7V to 6V
• 8-lead (3mm × 3mm) plastic DFN package
• 0°C to 70°C temperature rating
