LTC2054/LTC2055 - Single/Dual Micropower Zero-Drift ...

1 LTC2054/LTC2055 . Single/Dual Micropower Zero-Drift operational Amplifiers FEATURES DESCRIPTION. n Supply Current 150 A (Max per Ampli er) The LTC 2054/LTC2055 are low power, low noise, single/. Guaranteed from 40 C to 85 C dual, Zero-Drift operational ampli ers with an extended n Offset Voltage 3 V (Max, 40 C to 85 C) temperature version (LTC2054MP) that has guaranteed n Offset Voltage Drift 30nV/ C (Max, 40 C to 85 C) speci cations from 55 C to 150 C. They are available n Guaranteed Speci cations from 55 C to 150 C in TSOT-23 (ThinSOT ) and MS8 packages. For space (LTC2054MP) limited applications, the LTC2055 is also available in a n Common Mode Input Range from V to V + 3mm 3mm dual ne pitch leadless package n Output Swings Rail-to-Rail (DFN).

2 They operate from a single minimum supply n Voltage Gain: 140dB (Typ) and support 5V applications. The current consumption n PSRR and CMRR: 130dB (Typ) is typically 150 A for the LTC2054 and 130 A/amp for n Input Bias Current: 1pA (Typ, 25 C) the LTC2055. n Noise: VP-P ( to 10Hz Typ) The LTC2054/LTC2055 , despite their miniature size, feature n Supply Operation: uncompromising DC performance. The maximum input to 6V ( LTC2054/LTC2055 ) offset voltage and offset drift are V and 30nV/ C over to (LTC2054HV/LTC2055HV) the 40 C to 85 C industrial temperature range. The almost n Low Pro le (1mm) TSOT-23, MS8 and zero DC offset and drift are supported with a power supply 3mm 3mm DFN Packages rejection ratio (PSRR) and common mode rejection ratio APPLICATIONS (CMRR) of 130dB (typ).

3 N Thermocouple Ampli ers The input common mode voltage ranges from the negative n Electronic Scales supply up to typically below the positive supply. The n Medical Instrumentation open-loop gain is typically 140dB. The LTC2054/LTC2055 . n Strain Gauge Ampli ers also feature a VP-P DC to 10Hz noise and a 500kHz n High Resolution Data Acquisition gain-bandwidth product. n DC Accurate RC Active Filters L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
