AD8542ARMZ, Operational Amplifiers - Op Amps DUAL, LOW PWR RAIL/RAIL OP AMP

AD8542 is a dual channel, rail-to-rail input and output, single-supply amplifier. Very low input bias currents enable this amplifier to be used for integrators, photodiode amplifiers, piezoelectric sensors, and other applications with high source impedance. Rail-to-rail inputs and outputs are useful to designers buffering ASICs in single-supply systems. This amplifier is optimized to maintain high gains at lower supply voltages, making them useful for active filters and gain stages. • Single-supply operation is 2.7V to 5.5V• Low supply current/amplifier is 45µA typ at (VS = 5V, VCM = 2.5V, TA = 25°C)• Wide bandwidth is 1MHz, slew rate is 0.8V/µs typ at (RL = 100Kohm)• Settling time is 5µs typ at (to 0.01%, 1V step)• Unity gain stable, no phase reversal• Offset voltage is 1mV• Input bias current is 4pA• Voltage noise density is 42nV/√Hz typ at (f = 1kHz)• Operating temperature range is -40°C to +125°C• Packaging style is 8-lead MSOP
