Product details
Overview
TLC274BIN from Texas Instruments is a precision quad CMOS operational amplifier optimized for single-supply operation, featuring 10 mV max input offset voltage (C-suffix), 10.8 nV/√Hz input voltage noise at 1 kHz, >10¹² Ω input impedance, and rail-to-rail output swing down to ground - used in sensor signal conditioning, industrial analog front-ends, and low-power data acquisition systems.
For engineers reviewing the TLC274BIN datasheet, TLC274BIN pinout, TLC274BIN application, or TLC274BIN equivalent, key selection considerations include its 3–16 V single-supply range, –0.1 V to 3.5 V common-mode input range (at VDD = 5 V), 0.5 V/μs slew rate, 4.5 MHz unity-gain bandwidth, and PDIP-14 package compatibility with legacy through-hole layouts.
Technical Context
The TLC274BIN employs a polysilicon-gate CMOS process enabling ultra-low input bias current (<60 pA typ), latch-up immunity, and stable offset voltage drift (0.3 μV/°C). Its input stage supports common-mode voltages extending below ground, while the output stage delivers full swing to GND under load - critical for single-supply instrumentation interfaces.
Designed as a cost-effective BiFET/NFET alternative, it achieves boosted slew rate and speed without sacrificing precision: input offset voltage is graded across variants (TLC274 = 10 mV, TLC274B = 2 mV, TLC279 = 0.9 mV), with all C-suffix types rated for 0°C to 70°C operation and 3 V to 16 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max (25°C, TLC274C grade) - sets DC accuracy limit in high-gain sensor amplifiers |
| Input Voltage Noise | 10.8 nV/√Hz @ 1 kHz - enables low-noise amplification of microvolt-level signals (e.g., thermocouples) |
| Supply Voltage Range | 3 V to 16 V (0°C to 70°C) - supports direct interface with 3.3 V/5 V logic and battery-powered systems |
| Common-Mode Input Range | –0.1 V to 3.5 V @ VDD = 5 V - allows ground-referenced inputs in single-supply configurations |
| Output Voltage Swing | 0 V to 4.95 V @ VDD = 5 V, RL = 10 kΩ - delivers full dynamic range without negative rail |
| Slew Rate | 0.5 V/μs - sufficient for <100 kHz small-signal applications like active filters and transducer buffers |
| Unity-Gain Bandwidth | 4.5 MHz - supports stable closed-loop gain up to ~100× at audio and low-MHz frequencies |
Pinout & Package
N (PDIP-14) package: 19.3 mm × 9.4 mm through-hole dual in-line package with 0.3-inch row spacing, compatible with standard DIP sockets and wave-soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier channel 1 output - drives external load or next-stage input; rail-to-rail swing capability |
| 1IN–, 1IN+ | Input | Inverting/noninverting inputs for channel 1 - high-impedance nodes requiring guard-ring layout for leakage control |
| VDD | Power Supply | Positive supply rail (3–16 V); must be bypassed locally with 0.1 μF ceramic capacitor |
| GND | Power Supply | Negative supply or system ground reference; shared return path for all four amplifiers |
| 2IN+, 2IN–, 2OUT 3IN+, 3IN–, 3OUT 4IN+, 4IN–, 4OUT |
Input/Output | Independent I/O sets for channels 2–4 - enables multi-channel signal processing without external multiplexing |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply optimization | Input common-mode range extends below GND and output swings to GND - eliminates need for dual supplies in portable instrumentation |
| Ultra-high input impedance | >10¹² Ω typical - minimizes loading on high-impedance sources (e.g., pH electrodes, piezoelectric sensors) |
| Low input bias current | 10–60 pA typical (25°C) - reduces voltage error across high-value feedback networks (>1 MΩ) |
| ESD protection | Integrated circuitry per JEDEC JS-001 - withstands ≥2 kV HBM, reducing board-level transient protection requirements |
| Latch-up immunity | Designed-in robustness against I/O overvoltage-induced parasitic thyristor activation - improves field reliability in noisy environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464AIN | Lower offset (2 mV), higher quiescent current (520 μA/amplifier), rail-to-rail I/O, SOIC-14 only | Better DC accuracy but higher power - suited for battery-constrained designs needing tighter offset specs | Select TLV2464AIN when sub-2 mV offset and rail-to-rail input are required; avoid if PDIP-14 mounting or <1 mA total supply current is mandatory |
| LM324N | Bipolar input, 7 mV offset, no ESD protection, wider temp range (–40°C to 125°C), same PDIP-14 footprint | Higher input bias current (45 nA) limits use with >100 kΩ source impedances; lower cost for non-precision uses | Choose LM324N for cost-sensitive, non-critical analog functions where input impedance >10⁶ Ω is sufficient and ESD robustness is secondary |
Compared with TLV2464AIN and LM324N, TLC274BIN uniquely balances ultra-low bias current (<60 pA), CMOS input integrity, and PDIP-14 legacy compatibility - making it optimal for upgrading aging industrial sensor nodes without PCB redesign.

FAQ
What is the maximum operating temperature range for the TLC274BIN?
The TLC274BIN is a C-suffix device rated for 0°C to 70°C free-air operating temperature. It supports supply voltages from 3 V to 16 V within this range. Operation outside this range - including at –40°C or above 70°C - is not characterized or guaranteed, and the TLC274I (I-suffix) variant must be selected for industrial temperature operation.
Does the TLC274BIN support true rail-to-rail input?
No, the TLC274BIN does not support rail-to-rail input. Its common-mode input voltage range extends to –0.1 V (below GND) and up to 3.5 V when VDD = 5 V - meaning the upper limit is VDD – 1.5 V at temperature extremes. Input signals must remain within this validated range to avoid phase reversal or increased offset error.
Can the TLC274BIN drive a 10-kΩ load while maintaining rail-to-rail output swing?
Yes, the TLC274BIN delivers 0 V to 4.95 V output swing into a 10-kΩ load at VDD = 5 V and 25°C, per electrical characteristics table. At 70°C, minimum high-level output remains 3.0 V, and low-level output stays ≤50 mV - confirming functional rail-to-rail behavior for most precision buffering and ADC driving tasks.
Is the TLC274BIN pin-compatible with other quad op-amps in PDIP-14 packages?
The TLC274BIN shares the standard 14-pin PDIP pinout defined in TI's SLOS092E datasheet: pins 1–7 and 8–14 follow conventional quad op-amp ordering (1OUT, 1IN–, 1IN+, VDD, 2IN+, 2IN–, 2OUT, 3OUT, 3IN–, 3IN+, GND, 4IN+, 4IN–, 4OUT). This matches LM324N and TL074CP pinouts, enabling drop-in replacement where electrical specs align.
What is the typical input bias current of the TLC274BIN at room temperature?
The typical input bias current of the TLC274BIN is 10 pA at 25°C, with a maximum of 60 pA across the 0°C to 70°C operating range. This ultra-low value results from its polysilicon-gate CMOS process and enables accurate amplification of signals from high-impedance sources such as photodiodes and piezoelectric transducers without significant DC error.
