Product Details

The LTC®2058 is a dual, low noise, zero-drift operational amplifier that offers precision DC performance over a wide supply range of 4.75V to 36V. Offset voltage and 1/f noise are suppressed, allowing this amplifier to achieve a maximum offset voltage of 5μV and a DC to 10Hz input noise voltage of 200nVP-P (Typ). The LTC2058’s selfcalibrating circuitry results in low offset voltage drift with temperature, 0.025μV/°C (Max), and practically zero drift over time. The amplifier also features an excellent power supply rejection ratio (PSRR) of 150dB and a common mode rejection ratio (CMRR) of 150dB (Typ).

The LTC2058 provides rail-to-rail output swing and an input common mode range that includes the V– rail. In addition to low offset and noise, this amplifier features a 2.5MHz (Typ) gain-bandwidth product and a 1.6V/μs (Typ) slew rate.

Wide supply range, combined with low noise, low offset, and excellent PSRR and CMRR make the LTC2058 well suited for high dynamic-range test, measurement, and instrumentation systems.
