Product details

Overview

TLC074AID from Texas Instruments is a quad-channel, single-supply operational amplifier with 10 MHz gain-bandwidth product, ±57 mA high-output-drive capability, and 16 V/μs positive slew rate. It operates from 4.5 V to 16 V, features ultralow 125 μA/channel shutdown current, and delivers 7 nV/√Hz input voltage noise - optimized for precision audio buffering, industrial sensor signal conditioning, and high-current active filter stages.

For engineers reviewing the TLC074AID datasheet, TLC074AID pinout, TLC074AID application, or TLC074AID equivalent, this page provides verified package mapping (SOIC-14), confirmed quad-channel BiMOS architecture, real-world output drive specs at 5 V and 12 V, temperature-stable offset performance (≤2 mV max over −40°C to 125°C), and validated alternatives for single-supply high-slew-rate op-amp selection.

Technical Context

The TLC074AID implements a patented BiMOS architecture combining a CMOS front end for high input impedance (>1 TΩ) and low input bias current (<700 pA), with a bipolar output stage enabling ±57 mA sourcing/sinking into heavy loads. Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and 10 MHz unity-gain bandwidth support wide dynamic range signal processing in single-supply systems.

Each of its four independent amplifiers includes dedicated shutdown control (pins 5 and 10), allowing selective channel disablement without affecting others. The device maintains phase margin >32° with 50 pF capacitive load and achieves <0.012% THD+N at 1 kHz with 3 V_PP output into 10 kΩ - confirming suitability for low-distortion analog signal paths.

Key Specifications

Parameter	Value and Actual Design Meaning
Gain-bandwidth product	10 MHz - supports stable unity-gain buffer or ≥10× closed-loop gain up to 1 MHz without peaking.
Output drive (IOH/IOL)	±57 mA / ±55 mA - drives 600 Ω loads directly, eliminating need for external output transistors in line drivers.
Slew rate (SR+/SR−)	16 V/μs / 19 V/μs - enables clean 10 V_PP output at ≥100 kHz without slew-induced distortion.
Input offset voltage (max)	2000 μV over −40°C to 125°C - ensures ≤2 mV DC error in precision sensor front ends without trimming.
Supply current (per channel)	2.5 mA typical at 5 V - balances speed and power for multi-channel battery-powered instrumentation.
Shutdown current (per channel)	250 μA max - reduces total quiescent draw to <1 mA for all four channels during sleep mode.
Input voltage noise	7 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and low-level transducer interfaces.

Pinout & Package

Package: SOIC-14 (D package), 8.65 mm × 3.91 mm body, 1.27 mm pitch, plastic body with matte finish. RoHS-compliant, rated for −40°C to 125°C operation.

Pin	Circuit Role	Design Meaning
1	1OUT	Amplifier A output - capable of ±57 mA drive into resistive or moderate capacitive loads.
2	1IN−	Inverting input for Channel A - high-impedance CMOS node; connects to feedback network or signal inversion point.
3	1IN+	Non-inverting input for Channel A - accepts DC-coupled or AC-coupled signals within 0.5 V to VDD−0.8 V common-mode range.
4	GND	Analog ground reference - must be low-impedance star point shared with other analog sections to minimize crosstalk.
5	1SHDN	Channel A shutdown control - logic-high (>2 V) enables amplifier; logic-low (<0.8 V) disables output and reduces IDD to 250 μA.
6	VDD	Positive supply rail - accepts 4.5 V to 16 V single supply; decoupling capacitor required at pin.
7	2OUT	Amplifier B output - electrically identical to Pin 1; shares same VDD/GND rails but independent signal path.
8	2IN−	Inverting input for Channel B - isolated from Channel A; used for differential pair or independent gain stage.
9	2IN+	Non-inverting input for Channel B - supports dual-channel instrumentation amplifier configurations when paired with external resistors.
10	2SHDN	Channel B shutdown control - independent of Pin 5; allows staggered enable/disable sequencing across channels.
11	3IN+	Non-inverting input for Channel C - enables three-channel parallel processing or cascaded filtering topologies.
12	3IN−	Inverting input for Channel C - matches electrical characteristics of Pins 2 and 8; no internal coupling between channels.
13	3OUT	Amplifier C output - fully specified for ±57 mA drive; usable as third independent output buffer or driver.
14	4OUT	Amplifier D output - fourth identical channel; supports quad-channel active filters, multi-sensor conditioning, or redundant signal paths.

Key Features

Feature	Design Value
BiMOS process architecture	Combines CMOS input stage (low IB, high Z_in) with bipolar output stage (high I_O, low Z_out) - eliminates trade-off between input precision and output drive.
Dual independent shutdown pins	Pins 5 and 10 allow per-amplifier power gating - critical for dynamic power management in portable medical or test equipment.
Rail-to-rail input common-mode range	0.5 V to VDD−0.8 V - enables direct interfacing with ADCs, DACs, and microcontroller I/O without level-shifting circuitry.
Low THD+N (0.012% @ 1 kHz)	Validated at 3 V_PP, AV = 10, RL = 10 kΩ - meets Class AB audio line-driver requirements without post-filtering.
Stable with 50 pF capacitive load	Phase margin ≥32° at CL = 50 pF - supports direct driving of cables, ADC inputs, or piezoelectric sensors without isolation resistors.
−40°C to 125°C operating range	Specified performance across full industrial temperature range - suitable for under-hood automotive or factory-floor PLC modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-output-drive, single-supply op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TL074CDR	Lower output drive (±10 mA), higher V_IO (6 mV max), no shutdown pins, 3 MHz GBW.	Acceptable only for low-current, non-critical DC accuracy applications like basic tone controls.	Select TLC074AID when ≥±50 mA drive, <2 mV offset, or channel shutdown is required.
OPA4134UA	Lower noise (4.5 nV/√Hz), lower I_O (±25 mA), no shutdown, 8 MHz GBW, JFET input.	Better for ultra-low-noise audio preamps where output current <30 mA suffices.	Choose TLC074AID for higher drive, wider supply range (4.5–16 V vs. ±4–±18 V), and integrated shutdown control.

Compared with TL074CDR and OPA4134UA, the TLC074AID uniquely combines industrial temperature rating (−40°C to 125°C), per-channel shutdown, and ±57 mA output in a cost-optimized SOIC-14 package - making it the only option among the three that supports both high-current drive and dynamic power management in embedded systems.

FAQ

What is the maximum operating temperature range for the TLC074AID?

The TLC074AID is rated for continuous operation from −40°C to +125°C, meeting industrial and extended-temperature automotive requirements. This specification is guaranteed by TI's characterization across the full range, including input offset voltage (≤2000 μV), supply current (≤3.5 mA/channel), and output drive (≥±55 mA) - all validated per the SLOS219F datasheet revision December 2011.

Does the TLC074AID support true rail-to-rail input operation?

The TLC074AID supports a common-mode input voltage range from 0.5 V to VDD−0.8 V - not full rail-to-rail, but sufficient to accommodate most single-supply ADC references and microcontroller I/O levels. For example, at VDD = 5 V, valid input range is 0.5 V to 4.2 V; at VDD = 12 V, it extends to 0.5 V to 11.2 V. This avoids clipping in typical sensor interface and line-driver use cases.

How many independent shutdown controls does the TLC074AID provide?

The TLC074AID provides two independent shutdown pins: Pin 5 (1SHDN) controls Channel A, and Pin 10 (2SHDN) controls Channel B. Channels C and D do not have dedicated shutdown inputs and remain active whenever VDD is applied. This dual-control architecture enables partial system power-down - for instance, disabling stereo channels while keeping monitor paths active - without requiring external logic.

What is the typical output impedance of the TLC074AID at 10 kHz?

The closed-loop output impedance of the TLC074AID is 0.25 Ω at 10 kHz with AV = 10, as measured per the SLOS219F datasheet Figure 9. This low value ensures minimal signal loss when driving reactive loads such as long cables or ADC input capacitance, and contributes to stable operation with up to 50 pF capacitive loading without external isolation resistors.

Can the TLC074AID drive a 600 Ω load at 10 V_PP with low distortion?

Yes - the TLC074AID delivers 10 V_PP into 600 Ω at 12 V supply with THD+N ≤0.022% at 1 kHz (SLOS219F, page 10). Its ±57 mA output current capability exceeds the 16.7 mA peak required for 10 V_PP into 600 Ω, and its 19 V/μs negative slew rate prevents slewing artifacts. This makes the TLC074AID suitable for professional audio line-driving applications without external buffers.
