Input offset voltage is 200 µV typical, input bias current is 9 µA. The 9 µA bias is high compared to JFET-input amplifiers (picoamp range), so source impedance matters.
Output current capability is 110 mA typical. The SOT-23-5 package limits thermal dissipation — at 110 mA into a heavy load, junction temperature rise must be checked against the 85°C ambient limit.
No last-time-buy or discontinuation notice.
No. The voltage-feedback architecture is internally compensated. No external compensation network is needed for stable operation at the rated gains.
The THS4215DRBT is a voltage-feedback alternative with 970 V/µs slew rate and 350 MHz GBP, but it draws 19 mA supply current versus the OPA820IDBVR's 5.6 mA. The OPA859QDSGRQ1 is an automotive-grade JFET-input alternative with 900 MHz bandwidth and 1150 V/µs slew rate, qualified to AEC-Q100.
The SOT-23-5 pinout follows the standard single op-amp configuration: pin 1 is output, pin 2 is V–, pin 3 is non-inverting input, pin 4 is inverting input, pin 5 is V+. Verify against the datasheet for your specific layout.
