ADI LTC2055CDD#PBF

Zero-DriftRail-to-Rail500 кГц

Overview

The LTC2054/LTC2055CDD 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 SOT-23 (ThinSOT™) and MS8 packages. For space limited applications, the LTC2055CDD 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 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/LTC2055CDD also feature a 1.6μVP-P DC to 10Hz noise and a 500kHz gain-bandwidth product.
