OPA2323IDGKR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2323IDGKR is a dual-channel, low-voltage operational amplifier from the OPAx323 family. It features a zero-crossover input stage and rail-to-rail output capability. Key electrical parameters include a gain-bandwidth product of 20MHz, a typical slew rate of 33V/µs, and an input offset voltage of ±150µV. The device operates on a supply voltage range of 1.7V to 5.5V with a typical quiescent current of 1.6mA per channel. It provides high common-mode rejection ratio (CMRR) of 114dB and drives up to 150pF without oscillation.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'DGKR' corresponds to the VSSOP-8 package and tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance standards as indicated by the manufacturer. Ensure the procurement source provides valid traceability documentation for the Texas Instruments OPAx323 series.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high bandwidth and precision are required in low-voltage systems. The zero-crossover architecture is critical for applications demanding consistent performance across the entire input common-mode range. Consider the 20MHz gain-bandwidth product for fast settling requirements in data acquisition systems.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA2323IDGKR belongs to the OPAx323 family, which includes single (OPA323), dual (OPA2323), and quad (OPA4323) variants. This family is designed for low-voltage, high-bandwidth applications requiring rail-to-rail operation. The 'I' designation indicates industrial temperature range operation, while 'DGKR' specifies the VSSOP-8 package with reel packaging.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same family include OPA2323IDGKT (tube packaging). Other variants like OPA323 or OPA4323 offer different channel counts but share similar electrical characteristics. Verify package dimensions and thermal properties when substituting.
