LTC2058 36V, Low Noise Zero-Drift Operational Amplifier FEATURES DESCRIPTION n Supply Voltage Range: 4.75V to 36V The LTC 2058 is a dual, low noise, zero-drift operational n Offset Voltage: 5V (Maximum) amplifier that offers precision DC performance over a n Offset Voltage Drift: 0.025V/C (Maximum, 40C wide supply range of 4.75V to 36V. Offset voltage and 1/f to 125C) noise are suppressed, allowing this amplifier to achieve n Input Noise Voltage a maximum offset voltage of 5V and a DC to 10Hz input n 200nV , DC to 10Hz (Typ) noise voltage of 200nV (Typ). The LTC2058s self- P-P P-P n 9nV/Hz, 1kHz (Typ) calibrating circuitry results in low offset voltage drift with + n Input Common Mode Range: V 0.1V to V 1.5V temperature, 0.025V/C (Max), and practically zero drift n Rail-to-Rail Output over time. The amplifier also features an excellent power n Unity Gain Stable supply rejection ratio (PSRR) of 150dB and a common n Gain Bandwidth Product: 2.5MHz (Typ) mode rejection ratio (CMRR) of 150dB (Typ). n Slew Rate: 1.6V/s (Typ) The LTC2058 provides rail-to-rail output swing and an n A : 150dB (Typ) VOL input common mode range that includes the V rail. In n PSRR: 150dB (Typ) addition to low offset and noise, this amplifier features n CMRR: 150dB (Typ) a 2.5MHz (Typ) gain-bandwidth product and a 1.6V/s n Shutdown Mode (Typ) slew rate. APPLICATIONS Wide supply range, combined with low noise, low offset, n and excellent PSRR and CMRR make the LTC2058 well High Resolution Data Acquisition n suited for high dynamic-range test, measurement, and Reference Buffering n instrumentation systems.
