Single-Supply, Rail-to-Rail, Low Power, FET Input Op Amp AD820 PIN CONFIGURATIONS True single-supply operation Output swings rail-to-rail Input voltage range extends below ground Single-supply capability from 5 V to 36 V Dual-supply capability from ±2.5 V to ±18 V Excellent load drive Capacitive load drive up to 350 pF Minimum output current of 15 mA Excellent ac performance for low power 800 μA maximum quiescent current Unity-gain bandwidth: 1.8 MHz Slew rate of 3 V/μs Excellent dc performance 800 μV maximum input offset voltage 2 μV/°C typical offset voltage drift 25 pA maximum input bias current Low noise: 13 nV/√Hz @ 10 kHz NULL 1 NC 8 AD820 –IN 2 7 +VS +IN 3 6 VOUT 5 NULL –VS 4 TOP VIEW (Not to Scale) 00873-001 FEATURES NC = NO CONNECT Figure 1. 8-Lead PDIP NC 1 NC –IN 2 7 +VS +IN 3 6 VOUT 5 NC –VS 4 TOP VIEW (Not to Scale) NC = NO CONNECT 00873-002 8 AD820 Figure 2. 8-Lead SOIC_N and 8-Lead MSOP APPLICATIONS Battery-powered precision instrumentation Photodiode preamps Active filters 12-bit to 14-bit data acquisition systems Medical instrumentation Low power references and regulators GENERAL DESCRIPTION Offset voltage of 800 μV maximum, offset voltage drift of 2 μV/°C, typical input bias currents below 25 pA, and low input voltage noise provide dc precision with source impedances up to 1 GΩ. 1.8 MHz unity gain bandwidth, −93 dB THD at 10 kHz, and 3 V/μs slew rate are provided for a low supply current of 800 μA. The AD820 drives up to 350 pF of direct capacitive load and provides a minimum output current of 15 mA. This allows the amplifier to handle a wide range of load conditions. This combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile amplifier for the single-supply user. The AD820 is available in two performance grades. The A and B grades are rated over the industrial temperature range of −40°C to +85°C. The AD820 is offered in three 8-lead package options: plastic DIP (PDIP), surface mount (SOIC) and (MSOP). 1V 1V 20µs 100 90 10 0% 1V 00873-004 The AD820 is a precision, low power FET input op amp that can operate from a single supply of 5 V to 36 V, or dual supplies of ±2.5 V to ±18 V. It has true single-supply capability, with an input voltage range extending below the negative rail, allowing the AD820 to accommodate input signals below ground in the single-supply mode. Output voltage swing extends to within 10 mV of each rail, providing the maximum output dynamic range. Figure 3. Gain-of-2 Amplifier; VS = 5 V, 0 V, VIN = 2.5 V Sine Centered at 1.25 V Rev.
