Texas Instruments TLC27M7IPG4

Overview

TLC27M7IPG4 from Texas Instruments is a dual precision LinCMOS operational amplifier with 500 µV max input offset voltage at 25°C, rail-to-rail output swing (includes negative rail), and operation from 4 V to 16 V over −40°C to 85°C. It delivers low noise (32 nV/√Hz at 1 kHz), high input impedance (10¹² Ω typ), and low power consumption (2.1 mW at 5 V, 25°C), enabling use in battery-powered sensor signal conditioning and precision analog front-ends.

For engineers reviewing the TLC27M7IPG4 datasheet, TLC27M7IPG4 pinout, TLC27M7IPG4 application, or TLC27M7IPG4 equivalent, key selection criteria include its guaranteed 500 µV max V_IO across temperature, single-supply capability down to 4 V, common-mode input range extending below ground, and compatibility with industrial-grade thermal requirements.

Technical Context

The TLC27M7IPG4 uses silicon-gate LinCMOS process technology to achieve superior offset voltage stability versus metal-gate alternatives, with typical input offset drift of 0.1 µV/month including first 30 days. Its architecture supports true single-supply operation with common-mode input voltage range extending below the negative rail (GND) - confirmed for I-suffix devices at −0.2 V minimum.

It integrates ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2) and designed-in latch-up immunity. Absolute maximum ratings include ±30 mA output current per amplifier and 18 V supply voltage, with unlimited short-circuit duration at ≤25°C when dissipation limits are observed.

FAQ

What is the maximum input offset voltage specification for TLC27M7IPG4 across its full operating temperature range?

The TLC27M7IPG4 has a maximum input offset voltage of 500 µV at 25°C. Over its full −40°C to +85°C operating range, the datasheet specifies a maximum of 2000 µV (2 mV) under worst-case conditions with V_DD = 5 V and R_S = 50 Ω. This value reflects the combined effect of initial trim, temperature drift (1.7 µV/°C), and process variation.

Does TLC27M7IPG4 support true single-supply operation with inputs below ground?

Yes, the TLC27M7IPG4 supports true single-supply operation with its common-mode input voltage range extending to −0.2 V below GND at 25°C (and −0.2 V minimum over full temperature range). This allows direct connection of transducer outputs or AC-coupled signals without level-shifting circuitry - a key feature confirmed for I-suffix devices in the datasheet's recommended operating conditions table.

What is the typical supply current consumption of TLC27M7IPG4 at 5 V and 25°C?

The typical supply current for TLC27M7IPG4 is 210 µA per amplifier (420 µA total for both amplifiers) at V_DD = 5 V and T_A = 25°C with no load. The datasheet specifies a maximum of 560 µA total under these conditions. This low quiescent current makes the TLC27M7IPG4 suitable for battery-powered instrumentation and always-on sensor nodes.

Can TLC27M7IPG4 drive a 100 kΩ load while maintaining rail-to-rail output swing?

Yes, the TLC27M7IPG4 is specified to deliver rail-to-rail output swing into a 100 kΩ load. At V_DD = 5 V and 25°C, the low-level output voltage (V_OL) is guaranteed ≤50 mV with I_OL = 0, confirming operation down to GND. The high-level output (V_OH) reaches ≥3.0 V under the same conditions, leaving ~2 V headroom to V_DD. Performance remains valid across the full −40°C to +85°C range.

Is the TLC27M7IPG4 pin-compatible with other devices in the TLC27Mx family?

Yes, all TLC27Mx dual op-amps - including TLC27M2, TLC27M7, and their C/I/M suffix variants - share identical 8-pin PDIP (PG4), SOIC (D), and TSSOP (PW) pinouts. The TLC27M7IPG4 is fully pin-compatible with TLC27M7CP, TLC27M2IPG4, and other members of the family in the same package, enabling direct substitution where performance and temperature requirements align.
