Product details

Overview

TLC27M2BIDG4 from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 2 mV max input offset voltage at 25°C, −40°C to 85°C operating range, and rail-to-rail output swing down to the negative rail. It delivers low power (2.1 mW typ at 5 V), high input impedance (10¹² Ω), and low noise (32 nV/√Hz at 1 kHz), making it suitable for battery-powered sensor signal conditioning and industrial analog front-ends.

For engineers reviewing the TLC27M2BIDG4 datasheet, TLC27M2BIDG4 pinout, TLC27M2BIDG4 application, or TLC27M2BIDG4 equivalent, key selection criteria include its guaranteed 2 mV V_IO over temperature, single-supply operation from 4 V to 16 V, common-mode input range extending below ground, and SOIC-8 packaging with industry-standard footprint compatibility.

Technical Context

The TLC27M2BIDG4 implements silicon-gate LinCMOS process technology to achieve stable offset voltage drift (0.1 µV/month) and latch-up immunity. Its input stage supports common-mode voltages down to −0.2 V (at V_DD = 5 V), enabling true single-supply transducer interfacing without level-shifting circuitry.

Each amplifier provides unity-gain bandwidth of 525 kHz (typ at 5 V), slew rate of 0.4 V/µs (typ), and phase margin of 40° - characteristics optimized for stable closed-loop operation in active filters, precision gain blocks, and low-frequency instrumentation circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Offset Voltage	2 mV max at 25°C; ensures ≤2 mV DC error in precision DC-coupled amplification stages
Supply Voltage Range	4 V to 16 V across −40°C to 85°C; enables direct use with 5 V or 12 V industrial rails
Common-Mode Input Range	Extends to −0.2 V (at V_DD = 5 V); allows sensing signals referenced to ground in single-supply systems
Output Voltage Swing	Includes negative rail (V_OL ≤ 50 mV at I_OL = 0); supports full-scale signal recovery near 0 V
Input Bias Current	0.6 pA typ at 25°C; minimizes voltage drop across high-impedance sensor sources (e.g., pH electrodes)
Supply Current	210 µA typ per amplifier at 25°C; enables multi-channel low-power monitoring with <1 mA total quiescent draw
Input Noise Voltage	32 nV/√Hz at 1 kHz; preserves SNR in low-level signal amplification (e.g., thermocouple outputs)

Pinout & Package

Package: SOIC-8 (D package), surface-mount, 150 mil width, JEDEC MS-012AC compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amplifier 1)	Accepts feedback or differential signal path for first op-amp; high-impedance node requiring guarded layout
2	Non-Inverting Input (Amplifier 1)	Reference or sensor input node for first op-amp; supports common-mode range down to −0.2 V
3	Output (Amplifier 1)	Delivers rail-to-rail output swing; capable of sourcing/sinking ±30 mA for driving 100 kΩ loads
4	GND	Analog ground reference; must be connected to low-impedance system ground plane to maintain CMRR >60 dB
5	Non-Inverting Input (Amplifier 2)	Independent input for second op-amp; electrically isolated from Amp 1 inputs per datasheet layout guidance
6	Inverting Input (Amplifier 2)	Feedback node for second amplifier; shares same V_IO and bias current specs as Pin 1
7	Output (Amplifier 2)	Second independent output; identical AC/DC performance to Pin 3 under matched load conditions
8	V_CC	Positive supply rail; accepts 4–16 V; requires local 0.1 µF ceramic decoupling placed ≤5 mm from pin

Key Features

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV272IDR	Lower V_IO (1.5 mV max), lower supply current (110 µA), but narrower supply range (2.7–16 V) and no −40°C to 85°C guarantee for V_IO spec	Better suited for ultra-low-power portable designs where 2.7 V start-up is required	Select TLV272IDR only if sub-120 µA per amplifier is mandatory and V_IO stability at cold temperature is not critical
OPA2333AIDR	Zero-drift architecture, 12 µV max V_IO, but higher supply current (17 µA per amp) and limited output drive (±25 mA)	Ideal for high-accuracy medical sensors requiring µV-level DC precision over time and temperature	Choose OPA2333AIDR when long-term V_IO drift must be <0.02 µV/°C and 12-bit+ accuracy is non-negotiable

Compared with TLV272IDR and OPA2333AIDR, the TLC27M2BIDG4 offers the best balance of guaranteed 2 mV V_IO across −40°C to 85°C, 4–16 V supply flexibility, and proven robustness in industrial control environments - without requiring zero-drift complexity or ultra-low-power trade-offs.

FAQ

What is the maximum input offset voltage specification for TLC27M2BIDG4 over temperature?

The TLC27M2BIDG4 has a maximum input offset voltage of 2 mV at 25°C and 3 mV across the full −40°C to 85°C operating range, as specified in the "Electrical Characteristics" table for I-suffix devices under V_DD = 5 V conditions. This guaranteed limit enables predictable DC error budgeting in precision analog designs without calibration.

Does TLC27M2BIDG4 support true single-supply operation with inputs below ground?

Yes, the TLC27M2BIDG4 supports common-mode input voltages down to −0.2 V (at V_DD = 5 V) and −0.2 V (at V_DD = 10 V) across its full temperature range, allowing direct connection of ground-referenced sensors like thermocouples or bridge outputs without level-shifting circuitry - a key feature confirmed in the "Recommended Operating Conditions" table.

What package type and footprint does TLC27M2BIDG4 use?

The TLC27M2BIDG4 uses an SOIC-8 (D) package with 150-mil body width and standard JEDEC MS-012AC dimensions. Its pinout matches industry-standard dual op-amp footprints, enabling drop-in replacement for LM2904, TLC272, and similar SOIC-8 dual amplifiers in existing PCB layouts.

How does the input bias current of TLC27M2BIDG4 impact high-impedance sensor interfaces?

The TLC27M2BIDG4 exhibits 0.6 pA typical input bias current at 25°C, rising to 200 pA at 85°C. This ultra-low value minimizes voltage error across high-impedance sources (e.g., >1 MΩ pH electrodes or piezoelectric sensors), preserving signal integrity without requiring guard traces or active bias cancellation networks.

Is TLC27M2BIDG4 qualified for automotive applications?

No, the TLC27M2BIDG4 is characterized for −40°C to 85°C operation (I-suffix) and is not AEC-Q200 qualified. While it meets industrial temperature requirements, automotive-grade alternatives such as TLV272QDRQ1 (AEC-Q100 qualified) should be selected for under-hood or safety-critical vehicle systems.
