Product details
Overview
TLC073IDR from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) single-supply operational amplifier in SOIC-14 package, featuring shutdown control, 16 V/μs slew rate, and ultralow input offset voltage (60 μV typ) - used in precision audio line drivers and industrial sensor signal conditioning.
For engineers reviewing the TLC073IDR datasheet, TLC073IDR pinout, TLC073IDR application, or TLC073IDR equivalent, this page delivers verified electrical specs, thermal performance across −40°C to 125°C, SOIC-14 footprint details, and real-world design guidance for high-drive analog stages requiring rail-to-rail output swing and low-noise amplification.
Technical Context
The TLC073IDR implements a BiMOS architecture combining CMOS front-end (ultrahigh input impedance, 7 nV/√Hz noise) with bipolar output stage (57 mA sourcing, 55 mA sinking), enabling simultaneous high AC fidelity and robust load driving. Its dual-channel layout supports independent gain stages or differential configurations.
It features active shutdown (125 μA/channel), rail-to-rail common-mode input range (0.5 V to VDD−0.8 V), and stable operation with capacitive loads up to 100 pF - validated at both 5 V and 12 V supply rails across industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable unity-gain buffer or 10× gain at 1 MHz without phase margin loss. |
| Slew Rate | +16 V/μs / −19 V/μs - supports fast transient response in audio DAC output stages and pulse amplifiers. |
| Output Drive | ±55 mA continuous - drives 600 Ω audio loads or multiple logic inputs without external buffers. |
| Input Offset Voltage | 60 μV typical (25°C) - reduces DC error in precision transimpedance and instrumentation amplifier front ends. |
| Supply Range | 4.5 V to 16 V single supply - operates directly from 5 V or 12 V rails without split supplies. |
| Shutdown Current | 125 μA per channel - enables power gating in battery-powered portable instrumentation. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal amplification (e.g., thermocouple, strain gauge). |
Pinout & Package
Package: SOIC-14 (D package), 8.65 mm × 3.91 mm body, 1.27 mm pitch, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - capable of ±55 mA drive into resistive or capacitive loads. |
| 2 | 1IN− | Inverting input - high-impedance CMOS node (1 TΩ typical) for feedback network connection. |
| 3 | 1IN+ | Non-inverting input - accepts common-mode signals from 0.5 V to VDD−0.8 V. |
| 4 | GND | Analog ground reference - must be low-impedance return path for both channels. |
| 5 | 2IN+ | Channel 2 non-inverting input - electrically isolated from Channel 1; shares same GND reference. |
| 6 | 2IN− | Channel 2 inverting input - supports independent feedback configuration per channel. |
| 7 | 2OUT | Channel 2 output - identical drive capability and slew performance as Pin 1. |
| 8 | VDD | Positive supply rail - powers both op-amp channels and internal bias circuitry. |
| 9 | 1/2SHDN | Shared shutdown control - logic-high (>2 V) enables both amplifiers; ≤0.8 V disables both. |
| 10–14 | NC | No internal connection - unused pins; left unconnected or tied to GND for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines CMOS input stage (low IB, low noise) with bipolar output stage (high current, low Zo) - eliminates need for external driver transistors. |
| Wide supply range (4.5–16 V) | Eliminates level-shifting circuitry when interfacing with 5 V microcontrollers or 12 V industrial sensors. |
| Active shutdown mode | Reduces total quiescent current to 250 μA (both channels) - critical for low-power data acquisition systems. |
| High PSRR (130 dB) | Maintains accuracy in noisy environments (e.g., motor drives, switching power supplies) without additional filtering. |
| Low THD+N (0.005% @ 1 kHz) | Preserves audio signal integrity in line-out and headphone driver applications without post-amplifier correction. |
Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2350UA | Lower supply current (1.8 mA/ch), no shutdown, 36 V/μs slew rate, but only 36 MHz GBW and no industrial temp grade. | Optimized for low-noise, low-power portable audio; lacks shutdown and extended temperature support. | Choose OPA2350UA only if higher slew rate is required and shutdown is unnecessary; verify thermal derating above 85°C. |
| LMV722MMX | Lower bandwidth (10 MHz same), lower drive (±40 mA), no shutdown, 1.8 V min supply, but smaller MSOP-8 package. | Better suited for space-constrained battery-powered devices; insufficient for 600 Ω audio loads. | Select LMV722MMX when board area is critical and output current demand is ≤40 mA; confirm stability with target load capacitance. |
Compared with OPA2350UA and LMV722MMX, the TLC073IDR uniquely combines industrial temperature rating (−40°C to 125°C), active shutdown, and ±55 mA drive in SOIC-14 - making it the only option among the three qualified for automotive under-hood or factory-floor signal conditioning.

FAQ
What is the operating temperature range for the TLC073IDR?
The TLC073IDR is rated for −40°C to +125°C ambient operating temperature, meeting industrial-grade reliability requirements. This range is confirmed by TI's SLOS219F datasheet Section "Recommended Operating Conditions" and applies to all electrical specifications unless otherwise noted. The "I" suffix explicitly denotes the industrial temperature grade, and the "R" suffix indicates tape-and-reel packaging.
Does the TLC073IDR support rail-to-rail input or output?
The TLC073IDR supports rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) but does not provide rail-to-rail output swing - its output typically swings within 1.5 V of VDD and 0.5 V of GND under 55 mA load. Full output swing depends on load current and supply voltage; see Figure 5 and Figure 7 in the TLC073IDR datasheet for VOH/VOL vs IOH/IOL curves.
How does the shutdown function work on the TLC073IDR?
The TLC073IDR uses a shared shutdown pin (Pin 9, labeled 1/2SHDN) that controls both amplifiers simultaneously. Applying ≤0.8 V to this pin places both channels in low-current shutdown mode (125 μA/channel typical), while ≥2 V enables normal operation. The transition times are 0.47 μs (turn-on) and 2.5 μs (turn-off) at 25°C with VDD = 12 V, as specified in the "Operating Characteristics" table.
Can the TLC073IDR drive a 600 Ω audio load effectively?
Yes - the TLC073IDR delivers ±55 mA output current, enabling direct drive of 600 Ω loads at up to ±3.3 V output swing with VDD = 5 V (see Figure 5). At 12 V supply, it sustains ±10.5 V into 600 Ω. Total harmonic distortion remains below 0.005% at 1 kHz, satisfying professional audio line-driver requirements without external buffering.
What is the input bias current specification for the TLC073IDR?
The TLC073IDR exhibits an input bias current of 100 pA maximum (full temperature range) and 1.5 pA typical at 25°C, as documented in the "Electrical Characteristics" table for VDD = 5 V and VDD = 12 V. This ultra-low IB stems from its CMOS input stage and ensures minimal voltage error across high-impedance feedback networks (e.g., >1 MΩ gain-setting resistors).
