60V Zero-Drift Operational Amplifier with 220nVP-P Noise
Achieves Widest Dynamic Range
MILPITAS, CA – August 22, 2013 – Linear Technology introduces the LTC2057HV, 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 5µV input offset voltage,
0.025µV/°C offset drift and 220nVP-P low frequency noise with no 1/f noise, the LTC2057HV
offers more than 140dB dynamic range while operating on a 60V (±30V) 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
36V, a lower supply version of LTC2057 is available.
Specified over a -40°C to 125°C temperature range, the LTC2057 and LTC2057HV offer
an optimal combination of low voltage noise, low current noise and low input bias current, while
the zero-drift architecture cancels 1/f noise. Spurious artifacts normally associated with zero-drift
amplifiers are suppressed, further extending the dynamic range, stability and useful signal
bandwidth. The input common-mode range includes the negative rail and the output swings railto-rail, making the LTC2057 suitable for single- and dual-supply industrial, instrumentation and
automotive applications.
The LTC2057 is specified for 30V supply operation while the LTC2057HV can operate
on supplies up to 60V. Both versions also work on 4.75V supplies and are fully specified over
-40°C to 85°C and -40°C to 125°C temperature ranges. The LTC2057 is available in 3mm x
3mm DFN, MSOP-8 and SOIC-8 packages, as well as an MSOP-10 package with a pinout that

enables a guard ring to be easily routed around the input to preserve the high precision and low
noise performance at high source impedance. Pricing starts at $1.54 each for the LTC2057 and
$2.19 each for the LTC2057HV in quantities of 1000. For more information, visit
