Product details

Overview

TLC27M2BCDG4 from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 2 mV max input offset voltage at 25°C, rail-to-rail output swing down to GND, and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers 0.4 V/µs slew rate, 32 nV/√Hz input noise at 1 kHz, and 525 kHz unity-gain bandwidth - ideal for low-power sensor signal conditioning in portable instrumentation.

For engineers reviewing the TLC27M2BCDG4 datasheet, TLC27M2BCDG4 pinout, TLC27M2BCDG4 application, or TLC27M2BCDG4 equivalent, key selection criteria include its C-suffix commercial temperature grade, D-package SOIC-8 footprint, single-supply capability with negative-rail input common-mode range, and verified 2 mV V_IO tolerance for cost-sensitive analog front-ends.

Technical Context

The TLC27M2BCDG4 implements a silicon-gate LinCMOS process enabling ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance (10¹² Ω), directly supporting high-impedance transducer interfaces without passive compensation. Its internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.2.

Designed for single-supply operation, it supports common-mode input voltage down to −0.2 V (with V_DD = 5 V), and output swing to within 50 mV of GND - eliminating need for level-shifting circuitry in battery-powered systems. Latch-up immunity is built-in per design.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Offset Voltage	2 mV max at 25°C - enables DC-coupled amplification of µV-level signals without nulling circuitry
Supply Voltage Range	3 V to 16 V - supports direct connection to single Li-ion, multi-cell alkaline, or industrial 12 V rails
Input Bias Current	0.6 pA typical at 25°C - preserves signal integrity in photodiode and piezoelectric sensor interfaces
Slew Rate	0.4 V/µs at V_DD = 5 V - sufficient for audio-band and slow control-loop applications
Unity-Gain Bandwidth	525 kHz at V_DD = 5 V - allows stable closed-loop gain up to ~100× at 5 kHz
Common-Mode Input Range	Extends to −0.2 V below GND - permits true single-supply operation with ground-referenced inputs
Output Voltage Swing	Within 50 mV of GND and 3.9 V (at V_DD = 5 V) - maximizes dynamic range in 5 V systems

Pinout & Package

Package: SOIC-8 (D package), surface-mount, 150 mil width, tape-and-reel compatible.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amplifier A)	High-impedance node accepting differential signal reference; requires guarding in high-Z layouts

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV272IDR	Lower V_IO (1.5 mV max), higher quiescent current (1.25 mA), rail-to-rail input/output	Requires tighter V_IO spec but consumes 6× more supply current	Select when rail-to-rail input is mandatory and power budget allows
LMV358IDR	Higher V_IO (3 mV max), lower cost, no negative-rail input capability	Lacks extended common-mode range below GND; unsuitable for true single-supply ground-referenced sensors	Select for cost-driven general-purpose amplification where input range ≥ GND suffices

Compared with TLV272IDR and LMV358IDR, the TLC27M2BCDG4 uniquely balances 2 mV V_IO, sub-nA bias current, and negative-rail input support - making it optimal for precision, low-power, single-supply sensor interfaces where input grounding is fixed.

FAQ

What is the maximum input offset voltage specification for TLC27M2BCDG4 at 25°C?

The TLC27M2BCDG4 has a maximum input offset voltage of 2 mV at 25°C, as specified in the electrical characteristics table under the TLC27M2BC column. This value applies across the full commercial temperature range (0°C to 70°C) with V_DD = 5 V, and is confirmed by TI's SLOS051E datasheet revision August 2008.

Does TLC27M2BCDG4 support true single-supply operation with inputs referenced to ground?

Yes, the TLC27M2BCDG4 supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range extends to −0.2 V (with V_DD = 5 V), allowing both inputs to operate at GND potential. This capability is explicitly documented in the recommended operating conditions table for the C-suffix variant in the TLC27M2BCDG4 datasheet.

What package type and pin count does TLC27M2BCDG4 use?

The TLC27M2BCDG4 uses an 8-pin SOIC (Small Outline Integrated Circuit) package, designated as the "D" package by Texas Instruments. This surface-mount package measures 3.9 mm × 4.9 mm with 1.27 mm lead pitch and is supplied in tape-and-reel format - fully compatible with automated PCB assembly processes.

Can TLC27M2BCDG4 drive capacitive loads up to 1000 pF without instability?

No, the TLC27M2BCDG4 is not characterized for direct driving of 1000 pF loads. The datasheet specifies stability with C_L = 20 pF in unity-gain configuration (Figure 1). Driving larger capacitive loads requires isolation via a series resistor or external compensation; unbuffered 1000 pF loads may cause peaking or oscillation due to phase margin reduction below 40°.

Is TLC27M2BCDG4 rated for operation beyond 70°C ambient temperature?

No, the TLC27M2BCDG4 is rated only for 0°C to 70°C ambient operation, as indicated by its "C" temperature suffix. For extended temperature ranges, engineers must select variants such as TLC27M2BIDR (−40°C to 85°C) or TLC27M2BMDR (−55°C to 125°C); the TLC27M2BCDG4 datasheet explicitly limits its operating free-air temperature to the commercial grade range.
