Zero drift op amp achieves ‘widest’ dynamic range
The LTC2057HV from Linear Technology is a zero drift amplifier with self calibrating circuitry that provides high dc precision and stability over changes in temperature, time, input range and supply voltage.
With 5µV input offset voltage, 0.025µV/°C offset drift and 220nVP-P low frequency noise with no 1/f noise, the amplifier is designed to offer more than 140dB dynamic range while operating on a 60V (±30V) supply.
According to Linear, this wide dynamic range enables tiny signals to be amplified in the presence of much larger signals without saturating the amplifier or losing precision.
The LTC2057 is available in 3 x 3mm DFN, MSOP-8, MSOP-10 and SOIC-8 packages.
A lower supply version is available for applications requiring supply voltages up to 36V.
