THS4552IPWR

Instrumentation, Op Amps, Buffer Amps Overview

The THS4552IPWR is a dual-channel low-noise precision differential amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.4 V and draws a typical supply current of 1.37 mA for both channels. The device features a high slew rate of 220 V/µs and a gain-bandwidth product of 135 MHz, supporting a 3dB bandwidth of 150 MHz. Input and output stages are rail-to-rail. Key electrical specifications include an input offset voltage of 265 µV, an input bias current of 1 µA, and a common-mode rejection ratio ranging from 93 dB to 110 dB. It is housed in a 16-TSSOP package with a width of 4.40 mm.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Dual-channel architecture providing two independent fully differential amplifiers in a single package.
• Rail-to-rail input and output capabilities allowing signal swing close to the supply rails.
• Low noise performance suitable for precision signal conditioning applications.
• High slew rate and wide bandwidth for handling fast-changing signals.

Instrumentation, Op Amps, Buffer Amps Applications

• Driving analog-to-digital converters (ADCs) in data acquisition systems
• Single-ended to differential conversion circuits
• Precision instrumentation front-ends

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IPWR corresponds to the TSSOP-16 package and tape-and-reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating temperature range of -40°C to +125°C aligns with your system environmental constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel solution is required for differential signaling with rail-to-rail I/O. Compare against the single-channel THS4551 if only one channel is needed or if a smaller QFN/VQFN package is preferred. Consider the 135 MHz gain-bandwidth product and 220 V/µs slew rate for bandwidth-intensive applications. Verify that the 16-TSSOP footprint fits your PCB layout constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The THS4552 belongs to the THS455x family of low-noise precision differential amplifiers from Texas Instruments. This family includes variants like the THS4551 (single channel) and other package options such as THS4552IPWT. These devices are designed to interface between single-ended sources and differential ADCs or drivers, offering improved common-mode noise rejection compared to standard operational amplifiers.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

THS4552IPWT is a verified substitute part number offering identical functionality in the same TSSOP-16 package but potentially different reel packaging specifications. Single-channel equivalents include the THS4551 series, though pin counts and package types differ significantly.
