TP5592-VR

Instrumentation, Op Amps, Buffer Amps Overview

The TP5592-VR is a dual-channel chopper-stabilized zero-drift operational amplifier manufactured by 3PEAK. It operates on a single supply voltage ranging from 1.8 V to 5.5 V or split supplies between ±0.9 V and ±2.75 V. The device features a maximum input offset voltage of 20 μV with an offset drift of 0.01 μV/°C. Key electrical parameters include a unity-gain bandwidth of 3.3 MHz, a slew rate of 2.5 V/μs, and a quiescent current of 470 μA per amplifier. It offers rail-to-rail input and output swing, high common-mode rejection ratio (CMRR) of 127 dB, and power supply rejection ratio (PSRR) of 130 dB. The component is housed in an MSOP8 package and supports an operating temperature range from −40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix matches the required package type, as the VR suffix indicates the MSOP8 variant. Confirm RoHS compliance and halogen-free status if environmental regulations apply. Ensure the design accounts for the specified ESD protection levels and thermal resistance characteristics during layout. Validate that the application environment stays within the defined absolute maximum ratings to maintain reliability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low-frequency precision and stability are critical requirements. The zero-drift technology makes it suitable for applications where standard amplifiers would suffer from significant offset drift. Consider the 3.3 MHz bandwidth and 2.5 V/μs slew rate for signal conditioning needs. Evaluate the 470 μA per channel power consumption against system energy constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The TP5592-VR belongs to the TP559x series of zero-drift operational amplifiers, which includes single (TP5591) and quad (TP5594) variants. This series utilizes an auto-calibration technique with a continuous-time operational amplifier to achieve low offset voltage and low noise. The dual-channel configuration allows for cost-effective implementation of differential circuits or dual-sensor interfaces in compact designs.
