TLC2252AIP

Instrumentation, Op Amps, Buffer Amps Overview

The TLC2252AIP is a dual operational amplifier from the TLC225xA series, manufactured by Texas Instruments using Advanced LinCMOS technology. It features rail-to-rail output performance and very low power consumption of 35 µA per channel. The device operates within a supply voltage range of ±2.2 V to ±8 V (4.4 V to 16 V total). Key electrical characteristics include a gain-bandwidth product of 200 kHz, a slew rate of 120 mV/µs, an input offset voltage of 850 µV maximum at 25°C, and an input bias current of 60 pA maximum. It provides an input voltage noise density of 19 nV/√Hz at 1 kHz and supports an operating temperature range from -40°C to +125°C in an 8-pin PDIP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IP' corresponds to the Plastic DIP (P) package variant with the industrial temperature range (-40°C to +125°C) and the A-grade offset voltage specifications (max 850 µV). Confirm that the ordering information matches the manufacturer's current datasheet revision SLOS176D. Ensure compatibility with the required supply voltage range and load conditions before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the TLC2252AIP when a dual-channel amplifier with rail-to-rail output is required alongside ultra-low power operation. This component serves as a direct upgrade over older CMOS amplifiers like the TLC27L2 or TS27L2, offering improved output dynamic range and lower noise. It is suitable for designs needing high input impedance and low offset voltage in battery-powered environments.

Instrumentation, Op Amps, Buffer Amps Part Context

The TLC2252AIP belongs to the TLC225x family of Advanced LinCMOS rail-to-rail operational amplifiers. While the standard TLC2252 offers a maximum input offset voltage of 1500 µV, the TLC2252A variant specifies a tighter maximum of 850 µV at 25°C. The 'I' suffix denotes the extended industrial temperature range, and 'P' indicates the plastic dual in-line package format.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Public confirmed substitute part numbers include TLC2252CP (commercial grade), TLC2252ID (industrial grade, higher offset), and TLC2252AQD (automotive grade). For pin-compatible upgrades with better drive capabilities, consider the TLV2432.
