Product details
Overview
TLC073AIDR 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 ultralow 125 μA shutdown current per channel - used in audio line drivers and industrial sensor signal conditioning.
For engineers reviewing the TLC073AIDR datasheet, TLC073AIDR pinout, TLC073AIDR application, or TLC073AIDR equivalent, this page delivers verified electrical specs, SOIC-14 terminal mapping, real-world use cases in single-supply instrumentation, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLC073AIDR integrates a CMOS front end for high input impedance and low noise (7 nV/√Hz at 1 kHz) with a bipolar output stage enabling ±55 mA drive into heavy loads. Its BiMOS architecture supports rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and operates across 4.5 V–16 V supply rails.
It features independent shutdown control per amplifier (SHDN pins 6 and 13), 1.9 mA typical supply current per channel, and stable unity-gain operation with ≥32° phase margin at 50 pF load - optimized for driving capacitive cables and ADC input buffers without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable closed-loop gain ≥10 at 1 MHz for anti-aliasing filter buffering. |
| Slew Rate | +16 V/μs / −19 V/μs - supports clean 10 VPP output at ≥100 kHz without slewing distortion in active filters. |
| Output Drive | IOH = 57 mA at VDD−1.5 V; IOL = 55 mA at 0.5 V - drives 600 Ω audio loads or multiple logic inputs directly. |
| Input Offset Voltage | Max 1400 μV (A-grade, 25°C) - ensures ≤1.4 mV DC error in precision transimpedance amplifiers. |
| Supply Range | 4.5 V to 16 V single supply - interoperable with 5 V microcontroller systems and 12 V industrial rails. |
| Shutdown Current | 125 μA per channel - reduces system standby power by >93% vs active mode (1.9 mA/channel). |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor interfaces (e.g., thermocouple amplification). |
Pinout & Package
Package: 14-pin SOIC (D package), body width 3.9 mm, RoHS-compliant, tape-and-reel (R suffix indicates reel packaging).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - capable of sourcing/sinking ±55 mA into resistive or capacitive loads. |
| 2 | 1IN− | Inverting input - high-impedance CMOS node (1 TΩ typical); accepts signals within 0.5 V to VDD−0.8 V. |
| 3 | 1IN+ | Non-inverting input - matched to Pin 2 for <1.4 mV offset; used for reference-biased sensor interfaces. |
| 4 | GND | Analog ground reference - must be low-impedance star point for noise-sensitive applications. |
| 5 | NC | No internal connection - left unconnected; not usable as thermal pad or auxiliary function. |
| 6 | 1SHDN | Amplifier A shutdown control - logic-high (>2 V) enables; ≤0.8 V disables (125 μA quiescent). |
| 7 | NC | No internal connection - electrically isolated; no routing or grounding required. |
| 8 | VDD | Positive supply rail - accepts 4.5–16 V; decoupling capacitor (0.1 μF) required at pin. |
| 9 | 2OUT | Amplifier B output - identical drive capability to Pin 1; supports dual-path signal processing. |
| 10 | 2IN− | Inverting input (Amplifier B) - independently configurable; enables differential output stages. |
| 11 | 2IN+ | Non-inverting input (Amplifier B) - matches Pin 10 for common-mode rejection in instrumentation amps. |
| 12 | NC | No internal connection - unused; no electrical or thermal function. |
| 13 | 2SHDN | Amplifier B shutdown control - independent logic control enables selective channel power gating. |
| 14 | NC | No internal connection - not bonded; no PCB trace or via needed. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines CMOS input (low IB, high Zin) with bipolar output (high Iout, low Zo) - eliminates need for external driver stages. |
| Independent dual shutdown | Separate SHDN pins (6 & 13) allow per-amplifier power control - critical for multi-stage power sequencing in portable gear. |
| Rail-to-rail input common-mode range | Operates with inputs as low as 0.5 V and as high as VDD−0.8 V - simplifies level-shifting in single-supply data acquisition. |
| High PSRR (100 dB) | Maintains <10 μV/V output variation over 4.5–16 V supply swing - enables direct use with noisy switching supplies. |
| Low THD+N (0.005% @ 1 kHz) | Preserves audio fidelity in line-driver applications without post-amplifier filtering or compensation. |
| Stable with 50 pF capacitive load | Phase margin ≥32° at CL = 50 pF - drives long traces, coaxial cables, or ADC input capacitance without compensation. |
Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |

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 |
|---|---|---|---|
| OPA2350EA/250G4 | Lower noise (5 nV/√Hz), lower supply current (4.4 mA/ch), but only ±20 mA output drive and no shutdown. | Better for low-noise, low-power portable instruments; unsuitable for driving heavy loads or requiring power gating. | Select when noise dominates over drive strength and shutdown is unnecessary. |
| LMV722MMX/NOPB | Higher GBW (15 MHz), lower supply voltage (2.7–5.5 V), but only ±12 mA output and no shutdown. | Ideal for 3.3 V embedded systems with moderate drive needs; incompatible with 12 V industrial rails or high-current loads. | Select for 3.3 V designs needing higher speed at lower voltage, where drive and shutdown are secondary. |
Compared with OPA2350EA/250G4 and LMV722MMX/NOPB, TLC073AIDR uniquely balances 10 MHz bandwidth, ±55 mA drive, and per-channel shutdown in a single SOIC-14 package - making it the only option among the three suitable for 12 V industrial line drivers with dynamic power control.

FAQ
What is the operating temperature range for TLC073AIDR?
The TLC073AIDR is rated for −40°C to +125°C ambient operation, confirmed by TI's "I-suffix" designation and validated across all electrical parameters in the SLOS219F datasheet. This extended range supports deployment in under-hood automotive modules and industrial control cabinets without derating.
Does TLC073AIDR support rail-to-rail output swing?
No - TLC073AIDR does not provide rail-to-rail output. Its output typically swings to within 1.5 V of VDD (VOH ≥ VDD−1.5 V at IOH = 57 mA) and to 0.5 V above GND (VOL ≤ 0.5 V at IOL = 55 mA). This is sufficient for driving 12 V ADC references or 5 V logic, but not for true 0–5 V full-scale outputs.
How is shutdown controlled on TLC073AIDR?
TLC073AIDR provides two independent shutdown pins: Pin 6 (1SHDN) for Amplifier A and Pin 13 (2SHDN) for Amplifier B. Driving either pin to ≤0.8 V disables its respective amplifier, reducing supply current to 125 μA per channel. A logic-high signal (>2 V) re-enables normal operation with 0.47 μs turn-on time.
Can TLC073AIDR drive a 600 Ω load at 10 VPP?
Yes - TLC073AIDR delivers ±55 mA output current, enabling it to sustain 10 VPP into 600 Ω (requiring ±8.3 mA) with headroom to spare. At VDD = 12 V, VOH remains ≥10.3 V and VOL ≤ 0.65 V under full load, preserving >90% of the intended signal amplitude.
What is the input common-mode voltage range for TLC073AIDR?
The input common-mode voltage range for TLC073AIDR is specified as 0.5 V to VDD−0.8 V across the full temperature range. At VDD = 5 V, this is 0.5 V to 4.2 V; at VDD = 12 V, it extends to 0.5 V to 11.2 V - supporting direct interfacing with sensors and DACs operating near supply rails.
