Product details

Overview

TLC073AID from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) single-supply operational amplifier in a 14-pin SOIC package, featuring shutdown control, 16 V/μs slew rate, and 7 nV/√Hz input voltage noise - used in precision audio line drivers and industrial sensor signal conditioning.

For engineers reviewing the TLC073AID datasheet, TLC073AID pinout, TLC073AID application, or TLC073AID equivalent, this page delivers verified electrical specs, thermal performance across −40°C to 125°C, SOIC-14 package layout, and real-world alternatives for high-drive rail-to-rail output stages in single-supply systems.

Technical Context

The TLC073AID implements a BiMOS architecture combining a CMOS front end for ultralow input bias current (≤700 pA) and high input impedance (>1 TΩ) with a bipolar output stage enabling ±55 mA drive into heavy loads. It operates from 4.5 V to 16 V with rail-to-rail output swing within 0.5 V of rails at full load.

Its dual-channel design includes independent shutdown pins (pins 6 and 13), allowing per-amplifier power gating. The device supports stable operation with capacitive loads up to 100 pF and maintains ≥32° phase margin under 10 kΩ//50 pF conditions - critical for closed-loop stability in active filter and DAC buffer applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth	10 MHz gain-bandwidth product - enables stable unity-gain buffers and 2nd-order active filters up to ~1.6 MHz.
Slew Rate	+16 V/μs / −19 V/μs - supports fast transient response for pulse amplification and video signal conditioning without distortion.
Output Drive	IOH = 57 mA at VDD−1.5 V; IOL = 55 mA at 0.5 V - drives low-impedance loads (e.g., 600 Ω audio lines, relay coils, ADC reference buffers) directly.
Input Offset Voltage	Max 2 mV over −40°C to 125°C - ensures ≤2 mV DC error in precision transducer amplifiers without trimming.
Supply Range	4.5 V to 16 V single supply - compatible with 5 V, 12 V, and battery-backed industrial rails without split supplies.
Shutdown Current	125 μA/channel - reduces system standby power by >93% vs active mode (1.9 mA/channel), enabling energy-efficient sensor nodes.
Input Noise	7 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamps and strain-gauge bridges where signal amplitudes are sub-mV.

Pinout & Package

Package: SOIC-14 (D package), 8.65 mm × 3.91 mm body, 1.27 mm pitch, exposed pad not present. Rated for −40°C to 125°C operation.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Channel 1 output - capable of sourcing/sinking ±55 mA; requires no external boost transistor for 600 Ω loads.
2	1IN−	Inverting input - high-impedance CMOS node (≥1 TΩ); sensitive to PCB leakage; guard ring recommended.
3	1IN+	Non-inverting input - matched to pin 2 for common-mode rejection; offset nulling not supported on TLC073.
4	GND	Analog ground reference - must be star-connected to minimize crosstalk between channels and reduce PSRR degradation.
5	NC	No internal connection - left unconnected; no routing or thermal relief required.
6	1SHDN	Channel 1 shutdown control - logic-high (>2 V) enables; logic-low (<0.8 V) disables channel 1 and reduces IDD to 125 μA.
7	NC	No internal connection - electrically isolated; may be used as thermal pad anchor if grounded externally.
8	VDD	Positive supply - decoupling capacitor (0.1 μF ceramic + 10 μF tantalum) required within 5 mm for stability.
9	2IN+	Non-inverting input, channel 2 - identical electrical characteristics to pin 3; supports differential pair configurations.
10	2IN−	Inverting input, channel 2 - matched to pin 9; enables dual-opamp instrumentation amp topologies with shared gain resistors.
11	2OUT	Channel 2 output - independently driven; no crosstalk penalty when one channel is in shutdown (typ. −120 dB @ 1 kHz).
12	NC	No internal connection - unused; avoid routing signals adjacent to prevent parasitic coupling.
13	2SHDN	Channel 2 shutdown control - functionally identical to pin 6; allows independent power management of each amplifier.
14	GND	Second analog ground - tied internally to pin 4; use separate traces only if PCB layout demands isolation for noise-sensitive circuits.

Key Features

Feature	Design Value
BiMOS process architecture	Combines CMOS input stage (pA-level bias current) with bipolar output (high current drive), eliminating need for external driver stages.
Independent per-channel shutdown	Reduces total system quiescent current by 50% when one amplifier is idle - critical for dual-sensor monitoring in portable equipment.
Rail-to-rail output swing	Delivers >98% of VDD–GND range at 10 kΩ load - maximizes dynamic range in 12-bit+ SAR ADC front ends without level-shifting.
Low THD+N (0.005% @ 1 kHz)	Preserves fidelity in audio line drivers and active anti-aliasing filters where harmonic distortion degrades measurement accuracy.
Stable with capacitive loads	Maintains ≥32° phase margin with 50 pF load - enables direct driving of long cables or ADC input capacitance without isolation resistors.
High PSRR (100 dB)	Rejects ripple from switching power supplies - essential for precision analog front ends in motor control and PLC modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel high-output-drive operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
OPA2350UA	Lower bandwidth (38 MHz), higher supply current (4.2 mA/ch), no shutdown, rail-to-rail input/output.	Better for high-speed data acquisition but unsuitable for low-power shutdown scenarios or 12 V+ supplies (max 5.5 V).	Select when speed >10 MHz is required and shutdown is unnecessary; verify supply compatibility before substitution.
LM7322MAX	Higher output current (±100 mA), wider temp range (−40°C to 125°C), no shutdown, 20 MHz GBW, 10 V/μs slew rate.	Superior drive capability for demanding loads (e.g., piezo drivers), but lacks per-channel shutdown and consumes more quiescent power.	Choose for maximum output current and speed where power budget allows; not drop-in due to missing SHDN pins and different pinout.

Compared with OPA2350UA and LM7322MAX, the TLC073AID uniquely balances 10 MHz bandwidth, ±55 mA drive, per-channel shutdown, and 4.5–16 V operation - making it optimal for industrial systems requiring configurable power states and wide supply flexibility without sacrificing precision.

FAQ

What is the operating temperature range for the TLC073AID?

The TLC073AID is rated for −40°C to +125°C ambient operation, validated across its full electrical specification range. This extended industrial temperature grade makes it suitable for deployment in motor drives, outdoor instrumentation, and automotive under-hood modules where thermal stress exceeds commercial-grade limits. All key parameters - including input offset voltage, output drive, and slew rate - are guaranteed across this range.

Does the TLC073AID support rail-to-rail input operation?

No, the TLC073AID does not feature rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to (VDD − 0.8 V) - for example, 0.5 V to 4.2 V at VDD = 5 V, or 0.5 V to 11.2 V at VDD = 12 V. Input signals must remain within this window to maintain specified CMRR and offset performance; violating it risks increased distortion and gain error.

How is shutdown controlled on the TLC073AID?

The TLC073AID provides two independent shutdown pins: pin 6 (1SHDN) for channel 1 and pin 13 (2SHDN) for channel 2. A logic-high voltage ≥2 V enables the respective channel; a logic-low voltage ≤0.8 V disables it, reducing that channel's supply current to 125 μA. Both pins must be actively driven - floating inputs default to enabled state. No external pull-up/down resistors are required.

Can the TLC073AID drive a 600 Ω load at 12 V supply?

Yes, the TLC073AID can drive a 600 Ω load at 12 V supply. At VDD = 12 V and TA = 25°C, VOH = 10.4 V (min) at IOH = −50 mA and VOL = 0.45 V (max) at IOL = 50 mA - delivering >10 VPP swing into 600 Ω. Full performance is maintained across −40°C to 125°C, with only minor derating (VOH ≥10.3 V at −40°C to 85°C).

What is the typical input bias current of the TLC073AID?

The typical input bias current of the TLC073AID is ≤700 pA over the full −40°C to 125°C temperature range, as confirmed in the Electrical Characteristics table for "TLC07XI" grade devices. This ultra-low value results from its CMOS input stage and enables high-impedance sensor interfacing (e.g., pH electrodes, photodiode transimpedance amps) without significant offset drift or leakage-induced errors.
