AD820AN IC Chip Single Supply , Rail to Rail Low Power FET-Input Op Amp

 

PRODUCT DESCRIPTION

The AD820 is a precision, low power FET input op amp that can operate from a single supply of +3.0 V to 36 V, or dual supplies of ±1.5 V to ±18 V. It has true single supply capability with an input voltage range extending below the negative rail, 50 0 10 15 5 1 10 0 30 20 25 35 40 45 2 3 4 5 6 7 8 9 INPUT BIAS CURRENT – pA NUMBER OF UNITS Figure 1. Typical Distribution of Input Bias Current 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.

 

Offset voltage of 800 µV max, offset voltage drift of 1 µV/°C, typ input bias currents below 25 pA and low input voltage noise provide dc precision with source impedances up to a Gigaohm. 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 three performance grades. The A and B grades are rated over the industrial temperature range of –40°C to +85°C. There is 3 V grade—the AD820A-3V, rated over the industrial temperature range.

 

The AD820 is offered in two varieties of 8-lead package: plastic DIP, and surface mount (SOIC).
