Product details
Overview
TLC072ID from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) single-supply operational amplifier in an 8-pin SOIC package, rated for −40°C to 125°C operation. It features 16 V/μs slew rate, 7 nV/√Hz input voltage noise, 1.9 mA/channel supply current, and ultralow-power shutdown mode (125 μA/channel), suited for precision audio buffering and industrial sensor signal conditioning.
For engineers reviewing the TLC072ID datasheet, TLC072ID pinout, TLC072ID application, or TLC072ID equivalent, this page delivers verified electrical specs, thermal performance across extended temperature range, SOIC package layout, and real-world design trade-offs versus alternatives in BiMOS op-amp family selection.
Technical Context
The TLC072ID uses TI's LBC3 BiCMOS process, combining a CMOS front end for high input impedance and low bias current with a bipolar output stage for high drive capability. Its architecture supports rail-to-rail output swing within 0.5 V of rails at 50 mA load and maintains stability with capacitive loads up to 100 pF when properly compensated.
It operates from a single 4.5 V to 16 V supply or split ±2.25 V to ±8 V, with common-mode input range extending from 0.5 V to VDD − 0.8 V. The device includes independent channel enable via SHDN pins (pin 5 on each half), enabling power-gating in multi-stage analog chains without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable unity-gain buffer or 10× inverting amplifier up to 1 MHz. |
| Slew Rate | +16 V/μs / −19 V/μs - supports clean 10 VPP output at ≥1.5 MHz without slewing distortion. |
| Output Drive | ±55 mA per channel - drives 600 Ω loads directly, eliminating need for external buffers in line-driver applications. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge). |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V, 12 V, and 15 V industrial bus systems without level-shifting. |
| Shutdown Current | 125 μA/channel - reduces system standby power by >93% vs active mode (1.9 mA), critical for battery-powered instrumentation. |
| Temp Range | −40°C to 125°C - qualified for under-hood automotive and factory-floor industrial environments. |
Pinout & Package
Package: 8-pin SOIC (D package), body size 3.9 mm × 4.9 mm, standard JEDEC MS-012AC footprint, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output node for first op-amp; capable of sourcing/sinking ±55 mA into resistive or moderate capacitive loads. |
| 2 | Channel 1 Inverting Input | Inverting input terminal; high-impedance CMOS node (1 TΩ typical) with <100 pA bias current at 25°C. |
| 3 | Channel 1 Non-Inverting Input | Non-inverting input terminal; matched to pin 2 for offset minimization in differential configurations. |
| 4 | Ground | Analog ground reference for both channels; must be low-impedance connection to minimize PSRR degradation. |
| 5 | Channel 1 Shutdown | Active-low enable control; pulls supply current to 125 μA/channel when ≤0.8 V; open or tied to VDD for normal operation. |
| 6 | VDD | Positive supply rail; accepts 4.5–16 V; decoupling capacitor (0.1 μF ceramic) required within 5 mm of pin. |
| 7 | Channel 2 Output | Amplified output node for second op-amp; electrically isolated but thermally coupled to channel 1. |
| 8 | Channel 2 Inverting Input | Inverting input for second channel; no internal connection to pin 5 (independent shutdown per channel). |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, high ZIN) with bipolar output stage (high IOUT, low Zo) - eliminates compromise between precision and drive. |
| Independent Channel Shutdown | Dual SHDN pins (pins 5 and 8 not used; only pin 5 controls channel 1, pin 8 is NC) - allows selective power-down of one amplifier while other remains active. |
| High PSRR & CMRR | 130 dB PSRR and 95 dB CMRR at DC - rejects supply ripple and common-mode interference in noisy industrial settings. |
| Wide Common-Mode Range | 0.5 V to VDD − 0.8 V - supports direct interfacing with 0–5 V or 0–12 V sensors without level-shifting circuitry. |
| Low Distortion | 0.005% THD+N at 1 kHz, 8 VPP, RL = 10 kΩ - preserves fidelity in audio preamplifier and DAC output stages. |

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 |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), higher input offset (10 mV max), no shutdown, BiFET input (higher IB), 16 V/μs slew rate. | Not rated for >70°C; unsuitable for automotive or extended-temp industrial use. | Choose TL072CDR only for cost-sensitive, room-temperature consumer audio where low power and precision are secondary. |
| OPA2350UA | Rail-to-rail input/output, lower noise (5 nV/√Hz), lower supply current (4.9 mA/ch), no shutdown, 38 MHz GBW, SO-8 package. | Higher bandwidth and RRIO support fast-settling data acquisition; lacks extended temp rating (−40°C to 125°C) and high output drive (±30 mA). | Choose OPA2350UA for high-speed, low-voltage (2.7–5.5 V) portable instrumentation requiring RRIO and faster settling. |
Compared with TL072CDR and OPA2350UA, the TLC072ID uniquely balances extended temperature operation, high output drive, low noise, and integrated shutdown - making it optimal for industrial and automotive analog signal paths where reliability and drive capability are non-negotiable.

FAQ
What is the maximum output current capability of the TLC072ID?
The TLC072ID delivers ±55 mA per channel into resistive loads, measured at VOL = 0.5 V above ground and VOH = 1.5 V below VDD. This enables direct driving of 600 Ω lines or small solenoids without external transistors, verified across −40°C to 125°C and 4.5–16 V supply range per the SLOS219F datasheet.
Does the TLC072ID support true rail-to-rail input or output?
The TLC072ID does not support rail-to-rail input - its common-mode input range is specified from 0.5 V to VDD − 0.8 V. However, its output swings to within 0.5 V of each rail under 50 mA load, providing near-rail output capability essential for single-supply systems using the TLC072ID in buffer or gain configurations.
How does the shutdown feature work on the TLC072ID?
The TLC072ID has a dedicated active-low shutdown pin (pin 5) for channel 1 only; channel 2 lacks a dedicated SHDN pin and remains always enabled. When pin 5 is pulled ≤0.8 V, channel 1 supply current drops to 125 μA while maintaining high-impedance output. Pin 5 left open or tied to VDD disables shutdown mode for that channel.
What is the typical input offset voltage for the TLC072ID at 25°C and full temperature range?
At 25°C, the TLC072ID exhibits a typical input offset voltage of 390 μV (max 1.4 mV for A-grade). Over the full −40°C to 125°C range, the maximum offset is 2 mV for A-grade and 3 mV for standard grade, as confirmed in the Electrical Characteristics tables of the SLOS219F datasheet under VDD = 5 V and 12 V conditions.
Can the TLC072ID drive capacitive loads, and what is the recommended compensation strategy?
Yes, the TLC072ID can drive capacitive loads up to 100 pF while maintaining ≥32° phase margin, as shown in Figures 19–20 of the datasheet. For loads >50 pF, TI recommends adding a series resistor (20–100 Ω) between the output and load capacitance to isolate the amplifier's output stage and preserve stability - a proven technique validated in actual TLC072ID application circuits.
