Texas Instruments TLC27L2ACPSG4

Overview

TLC27L2ACPSG4 from Texas Instruments is a precision dual CMOS operational amplifier in an 8-pin SOP package, featuring 5 mV max input offset voltage at 25°C, ultra-low 34 µA typical supply current (two amplifiers), 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 is used in low-power sensor signal conditioning for field transmitters.

For engineers reviewing the TLC27L2ACPSG4 datasheet, TLC27L2ACPSG4 pinout, TLC27L2ACPSG4 application, or TLC27L2ACPSG4 equivalent, key selection criteria include input offset voltage grade (5 mV), single-supply capability with extended common-mode range, ultra-low power consumption, LinCMOS™ input impedance (>10¹² Ω), and SOP-8 packaging compatibility with automated assembly.

Technical Context

The TLC27L2ACPSG4 implements Texas Instruments' silicon-gate LinCMOS™ process, delivering stable input offset voltage (drift ≤0.1 µV/month) and high DC precision without bipolar power penalties. Its dual-channel architecture supports independent signal paths with matched gain and offset characteristics across temperature.

It supports single-supply operation with common-mode input voltage extending 0.2 V below GND and output swing to within 50 mV of GND at 5 V supply. Internal ESD protection meets MIL-STD-883C, Method 3015.2 (2000 V HBM).

FAQ

What is the maximum input offset voltage specification for TLC27L2ACPSG4 at 25°C?

The TLC27L2ACPSG4 has a maximum input offset voltage of 5 mV at 25°C, as specified in the "Electrical Characteristics, VDD = 5V, C Suffix" table of the TI SLOS052E datasheet. This value applies across the full 0°C to 70°C operating range, with a worst-case of 6.5 mV at temperature extremes. The TLC27L2ACPSG4 is part of the A-grade variant, distinguishing it from the standard TLC27L2 (10 mV) and higher-precision B- and 7-grade versions.

Does TLC27L2ACPSG4 support true single-supply operation with inputs extending below ground?

Yes, the TLC27L2ACPSG4 supports true single-supply operation with its common-mode input voltage range extending to −0.2 V (i.e., 200 mV below GND) at 5 V supply, as confirmed in Section 5.3 "Recommended Operating Conditions" of the datasheet. This allows direct interfacing with ground-referenced sensors such as strain gauges or thermocouples without level-shifting circuitry. The TLC27L2ACPSG4 maintains this capability across its full 0°C to 70°C temperature range.

What is the typical supply current for TLC27L2ACPSG4 and how does it scale with supply voltage?

The TLC27L2ACPSG4 draws 34 µA typical supply current (for both amplifiers) at 5 V and 25°C, increasing to 46 µA at 10 V under identical conditions. This linear scaling reflects its CMOS bias architecture-no thermal runaway or exponential increase occurs. At 3 V minimum supply, IDD drops to ~24 µA, enabling sub-10 µW per amplifier operation. All values are measured with no load and verified in Sections 5.4 and 5.6 of the SLOS052E datasheet.

Is TLC27L2ACPSG4 pin-compatible with other variants in the TLC27Lx family?

Yes, the TLC27L2ACPSG4 is pin-compatible with all TLC27Lx dual op amps in the PS (SOP-8) package-including TLC27L2, TLC27L2B, and TLC27L7-per Table "Device Information" and Figure 4-1 in the SLOS052E datasheet. Pin functions (1IN+, 1IN−, 1OUT, GND, 2IN+, 2IN−, VDD) are identical across grades and suffixes. However, performance differences (e.g., VIO, bandwidth, temperature range) require validation for functional interchangeability in each target application.

What package type and dimensions does TLC27L2ACPSG4 use, and is it RoHS-compliant?

The TLC27L2ACPSG4 uses the PS package: an 8-pin small-outline plastic (SOP) with 150-mil body width, 1.27 mm lead pitch, and JEDEC MS-012AC footprint. It is RoHS-compliant and halogen-free, as confirmed in TI's official packaging documentation (SLMA002) and the "Mechanical, Packaging, and Orderable Information" section (Section 10) of SLOS052E. The "G4" suffix denotes green (lead-free) packaging per TI's standard ordering nomenclature.
