Texas Instruments TLC2272ACPWR

Overview

TLC2272ACPWR from Texas Instruments is a dual rail-to-rail output operational amplifier in TSSOP-8 package, delivering 2.2-MHz gain-bandwidth, 3.6-V/μs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, ±500 µA output drive, and 1-pA typical input bias current. It operates from ±2.2 V to ±8 V supplies and supports precision transducer interfacing in battery-powered handheld monitoring systems.

For engineers reviewing the TLC2272ACPWR datasheet, TLC2272ACPWR pinout, TLC2272ACPWR application, or TLC2272ACPWR equivalent, key selection criteria include rail-to-rail output swing (±4.91 V at ±5 V supply), low 950 µV max input offset voltage (TA = 25°C), 75 dB CMRR, 95 dB PSRR, and compatibility with single-supply ADC interface circuits requiring high common-mode input range down to VDD−.

Technical Context

The TLC2272ACPWR uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise (9 nV/√Hz). Its input stage supports common-mode voltage down to the negative rail, enabling direct sensing of ground-referenced signals without level-shifting circuitry.

It features unity-gain stable operation with 52° phase margin and 10 dB gain margin under 10 kΩ load and 100 pF capacitive load conditions. The device is fully specified for both single-supply (e.g., 5 V) and split-supply (e.g., ±5 V) operation across temperature ranges up to 125°C for industrial and automotive applications.

Key Specifications

Pinout & Package

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, designing and manufacturing analog and embedded processing chips for industrial, automotive, and consumer markets.

The TLC227x family was engineered as a performance upgrade to the TLC27x series, targeting precision analog signal conditioning in resource-constrained systems where rail-to-rail output, low noise, and micropower dissipation are critical.

FAQ

What is the maximum supply voltage range for the TLC2272ACPWR?

The TLC2272ACPWR supports a total supply voltage range of ±2.2 V to ±8 V in split-supply mode, or 4.4 V to 16 V in single-supply operation. Absolute maximum ratings specify ±8 V on VDD+ and VDD− pins individually. Exceeding these limits risks permanent damage, as confirmed in Section 6.1 of the SLOS190H datasheet.

Does the TLC2272ACPWR support rail-to-rail input capability?

No, the TLC2272ACPWR does not feature rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to (VDD+ − 1.5 V) on the positive side. At ±5 V supply, this yields a VICR of –5 V to +3.5 V. This design allows ground-referenced inputs in single-supply use while maintaining CMOS input stage robustness.

What is the guaranteed maximum input offset voltage for the TLC2272ACPWR over temperature?

The TLC2272ACPWR (A-grade variant) guarantees a maximum input offset voltage of 1500 µV across its full operating temperature range of –40°C to +125°C. At TA = 25°C, the limit is tighter: 950 µV maximum. These values are explicitly specified in Section 6.5 and 6.6 of the SLOS190H datasheet for VDD = 5 V and VDD± = ±5 V conditions.

Can the TLC2272ACPWR drive a 10-kΩ load while maintaining rail-to-rail output swing?

Yes, the TLC2272ACPWR maintains rail-to-rail output swing into 10-kΩ loads. At ±5 V supply and TA = 25°C, it delivers ±4.91 V output with 500 µA load (equivalent to 10-kΩ at ±4.91 V), per Section 6.6 VOM+ and VOM– specifications. Output swing degrades predictably with heavier loads: ±4.25 V at ±1 mA (5-kΩ equivalent).

Is the TLC2272ACPWR pin-compatible with the standard TLC2272CPWR?

Yes, the TLC2272ACPWR is pin-compatible with the TLC2272CPWR. Both share identical TSSOP-8 packaging, pin numbering, and pin functions per the "Pin Configuration and Functions" section (page 5) of the SLOS190H datasheet. The 'A' suffix denotes tighter input offset voltage specification (950 µV max vs. 2500 µV max), with no physical or functional pinout differences.
