OPA2325IDGKR

OPA2325IDGKR is TI’s dual operational amplifier in an 8-pin, lead-free package. The OPA2325 combines low power with rail-to-rail input and output, enabling reliable single-supply operation from near ground to the positive rail. It offers low offset voltage and drift, low input bias current, and good bandwidth for general amplification tasks.
Key points:
- Dual op-amp, 8-pin package (IDGKR indicates RoHS/lead-free version, with typical small-packaging/shipping options)
- Rail-to-rail input and output for 0-to-supply-swing operation
- Low quiescent current, suitable for battery-powered applications
- Unity-gain stable; suitable for buffering, active filters, sensor conditioning, and DAC/ADC front ends
- Good for compact, portable instrumentation and low-noise signal conditioning
Usage notes:
- Provide proper supply decoupling near V+ and V−
- Keep feedback paths short for best performance
If you need exact electrical specs (offset, bias, bandwidth, supply range) for a given design, consult the TI datasheet for the OPA2325IDGKR variant.

Here are the typical features of the OPA2325IDGKR (dual precision op-amp in an 8-pin VSSOP package):
- Dual op-amp with rail-to-rail input and output
- Chopper-stabilized (low offset voltage and ultra-low drift)
- Very low input bias current
- Low-noise performance
- Wide single-supply operating range (e.g., 1.8 V to 5.5 V)
- Wide input common-mode range including the negative rail
- Low quiescent current per channel
- Temperature range suitable for industrial use
- Small 8-pin VSSOP package (IDGKR variant: RoHS, lead-free, tape-and-reel)
- Suitable for precision sensor interfaces, instrumentation, and low-power analog signals
Note: For exact electrical values (offset, bias current, noise, bandwidth, etc.), consult the latest datasheet.

OPA2325IDGKR uses an 8-pin VSSOP (Very Small Outline Package) — the DGK variant. Size is about 3.0 x 3.0 mm; RoHS/lead-free; available in tape-and-reel (GKR).

- Pin count: 8 pins
- Function: Dual operational amplifier (two op-amps in one package)

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits and embedded processing solutions, headquartered in Dallas, Texas.

OPA2325IDGKR is a dual, rail-to-rail I/O, low-noise op-amp. Typical applications include:
