description
The LTC1052 is a low-noise chopper-stabilized operational amplifier manufactured using CMOS silicon-gate
technology. The device is well-suited for applications such as thermocouple amplifiers, strain-gauge amplifiers,
low-level signal processing, and medical instrumentation.
Chopper stabilization constantly corrects input offset voltage errors, including both errors in the initial input offset
voltage and errors in input offset voltage due to time, temperature, and common-mode input voltage. The
chopper circuitry is internal and completely transparent to the user. Only two external capacitors are required
to alternately sample and hold the offset correction voltage and the amplified input signal.
Low-frequency (1/f) noise is also improved by the chopping technique. Instead of noise increasing continuously
at a rate of 3 dB/octave, the internal chopping causes noise to decrease at low frequencies. Picoampere input
currents further enhance the performance of this device.
The C-suffix devices are characterized for operation from − 40°C to 85°C. The M-suffix devices are
characterized for operation over the full military temperature range of − 55°C to 125°C.
