AD648KR-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The AD648KR-REEL7 is a dual precision, low power BiFET operational amplifier manufactured by Analog Devices Inc. It features a maximum quiescent current of 400 µA and a maximum bias current of 10 pA when warmed up. The device offers a unity gain bandwidth of 1 MHz and a slew rate of 1.8 V/µs. Input offset voltage is specified at a maximum of 1.0 mV with a drift of 10 µV/°C for the K grade. It operates within a supply voltage range of ±4.5 V to ±18 V and is housed in an 8-lead Plastic SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific grade suffix (K) against design requirements for offset voltage and temperature range specifications. Confirm that the tape and reel packaging aligns with automated assembly equipment capabilities. Ensure ESD handling protocols are strictly followed during installation due to the sensitivity of the BiFET input stage.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low power consumption alongside high DC precision. The AD648KR-REEL7 is suitable for commercial temperature ranges (0°C to 70°C). Consider the 1 MHz bandwidth and 1.8 V/µs slew rate for signal conditioning tasks. Verify compatibility with existing PCB layouts if replacing legacy dual op amps like the LF442.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD648KR-REEL7 belongs to the AD648 family of dual precision BiFET operational amplifiers. This series is characterized by its ion-implanted FET input technology and laser wafer trimming. The KR suffix indicates the K grade variant packaged in an 8-lead Plastic SOIC format, supplied in tape and reel configuration for surface mount processing.
