ADI AD820BR

J-FETRail-to-Rail1,8 МГц

Overview

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 AD820BR 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 AD820BR 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 AD820BR is offered in three 8-lead package options: plastic DIP (PDIP), surface mount (SOIC) and (MSOP).
