Zero drift op-amp

18 September 2013 Analogue, Mixed Signal, LSI

The LTC2057HV from Linear Technology is a zero-drift amplifier featuring self-calibrating circuitry that provides high DC precision and stability over changes in temperature, time, input range and supply voltage. With 5 µV input offset voltage, 0,025 µV/°C offset drift and 220 nVP-P low frequency noise with no 1/f noise, the IC offers more than 140 dB dynamic range while operating on a 60 V (±30 V) supply. This wide dynamic range enables tiny signals to be amplified in the presence of much larger signals without saturating the amplifier or losing precision. For applications requiring supply voltages up to 36 V, a lower supply version is available.
