Texas Instruments TLC272BCPS

Overview

TLC272BCPS from Texas Instruments is a precision dual CMOS operational amplifier optimized for single-supply operation, featuring 2 mV max input offset voltage (25°C), 10.8 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It operates from 3 V to 16 V over 0°C to 70°C and delivers 4.5 MHz unity-gain bandwidth - ideal for sensor signal conditioning in portable instrumentation.

For engineers reviewing the TLC272BCPS datasheet, TLC272BCPS pinout, TLC272BCPS application, or TLC272BCPS equivalent, key selection criteria include its low-input-bias-current design (<60 pA), wide common-mode input range extending below ground, and compatibility with TTL/HCMOS supply rails - critical for battery-powered analog front-ends and precision DC-coupled amplification stages.

Technical Context

The TLC272BCPS uses a polysilicon-gate CMOS process to achieve ultra-high input impedance (>10¹² Ω) and low input bias current, enabling high-impedance source interfacing without significant error. Its input stage supports common-mode voltages down to –0.1 V (at VDD = 5 V), and output swings within 50 mV of ground under load - essential for true single-supply DC coupling.

It integrates ESD protection circuitry and latch-up immunity per JEDEC JESD78, with specified performance across temperature and supply variations: input offset drift ≤0.3 µV/°C (25°C to 70°C), CMRR ≥65 dB, and PSRR ≥65 dB - making it suitable for stable operation in mixed-signal industrial control nodes.

FAQ

What is the maximum input offset voltage specification for TLC272BCPS at 25°C?

The TLC272BCPS has a maximum input offset voltage of 2000 µV (2 mV) at 25°C, as specified in the Electrical Characteristics table for the "TLC272BC" grade under VDD = 5 V conditions. This value applies across the full operating temperature range (0°C to 70°C), with a worst-case of 3000 µV at extremes. The TLC272BCPS inherits this grading directly from the TLC272B C-suffix variant.

Does TLC272BCPS support true single-supply operation with input signals at ground potential?

Yes, the TLC272BCPS supports true single-supply operation with input signals at ground. Its common-mode input voltage range extends to –0.1 V (with VDD = 5 V), allowing the IN– and IN+ pins to accept signals referenced to V− (ground). This enables direct interfacing with ground-referenced sensors without level-shifting circuitry - a core design feature confirmed in Section 4.2 and Figure 6-2 of the datasheet.

What package type does TLC272BCPS use, and how does it differ from TLC272CDR?

TLC272BCPS uses the PS (SOP-8) package: 6.2 mm × 7.8 mm body with gull-wing leads. In contrast, TLC272CDR uses the D (SOIC-8) package: 4.9 mm × 6 mm. Both are surface-mount, but PS offers larger pad area and improved thermal dissipation. The "PS" suffix explicitly denotes the SOP-8 variant per TI's packaging nomenclature in Section 9 of the datasheet.

Can TLC272BCPS drive a 10 kΩ load while maintaining rail-to-rail output swing?

Yes, the TLC272BCPS delivers rail-to-rail output swing into a 10 kΩ load: VOL ≤ 50 mV and VOH ≥ 4.95 V (at VDD = 5 V, 25°C), as verified in Table 4.3. This performance holds across temperature (0°C to 70°C) and supply (3–16 V), enabling full-scale ADC interfacing without external level-shifting - a key advantage over older general-purpose op-amps.

Is TLC272BCPS suitable for battery-powered applications with supply voltages as low as 3 V?

Yes, the TLC272BCPS is fully specified for 3 V operation across 0°C to 70°C, meeting all key parameters including input offset voltage, CMRR, and output swing. Its low 1.12 mA typical supply current (two amplifiers, no load) and ability to operate down to 3 V make it well-suited for coin-cell or single-Li-ion powered devices - explicitly stated in the "Wide range of supply voltages" feature and Section 4.2.
