The LTC2053 is a high precision instrumentation amplifier with adjustable gain, low offset voltage, and small temperature drift. It is suitable for applications such as thermocouple amplifiers, electronic scales, and medical instrumentation.
The LTC2053 and LTC2053‑SYNC are high‑precision, rail‑to‑rail, zero‑drift instrumentation amplifiers with resistor‑programmable gain. They offer 116 dB CMRR independent of gain, low offset voltage (<10 µV) and low drift (<50 nV/°C), making them suitable for thermocouple amplifiers, medical instrumentation, strain‑gauge amplifiers, and high‑resolution data acquisition.
