Product details
Overview
TLC072AIDR 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, featuring 16 V/μs positive slew rate, 7 nV/√Hz input voltage noise, and ultralow-power shutdown mode (125 μA/channel). It operates from 4.5 V to 16 V and is used in precision audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring rail-to-rail output swing and robust load driving.
For engineers reviewing the TLC072AIDR datasheet, TLC072AIDR pinout, TLC072AIDR application, or TLC072AIDR equivalent, this page delivers verified electrical parameters, SOIC-8 terminal mapping, temperature-rated performance (−40°C to 125°C), real-world application contexts, and two validated alternative op-amps with documented functional and packaging differences.
Technical Context
The TLC072AIDR employs TI's patented LBC3 BiCMOS process, integrating a low-noise CMOS front end (1000 GΩ differential input resistance, 7 nV/√Hz noise) with a high-current bipolar output stage capable of ±55 mA drive into heavy loads. Its architecture supports stable unity-gain operation with 32°–42° phase margin across 0–50 pF capacitive loads.
It features true single-supply operation with common-mode input range extending from 0.5 V above ground to 0.8 V below VDD, enabling direct interfacing with microcontroller ADCs and DACs. The device includes independent channel enable/disable via SHDN pins, with fast turn-on (0.47 μs) and turn-off (2.5 μs) times at 12 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable closed-loop operation up to 10× gain at 1 MHz for audio and instrumentation amplifiers. |
| Slew Rate | +16 V/μs / −19 V/μs - supports clean 10-Vpp output at ≥100 kHz without slewing distortion in active filters or buffer stages. |
| Output Drive | ±55 mA per channel - drives 600 Ω audio loads or multiple logic inputs without external buffers. |
| Input Offset Voltage | Max 2 mV over −40°C to 125°C - ensures ≤20 mV error in 10× gain sensor amplifiers across full industrial temperature range. |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V, 12 V, and battery-backed industrial rails without split-supply circuitry. |
| Shutdown Current | 125 μA/channel - reduces system standby power by >93% vs active mode (1.9 mA/channel), critical for always-on monitoring nodes. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level transducer interfaces (e.g., thermocouples, strain gauges) without added filtering. |
Pinout & Package
Package: 8-pin SOIC (D package), surface-mount, RoHS-compliant, rated for −40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - delivers ±55 mA into loads; requires no series resistor for 600 Ω termination. |
| 2 | IN− A | Inverting input A - high-impedance (1000 GΩ) node; sensitive to PCB leakage and guarding requirements. |
| 3 | IN+ A | Non-inverting input A - accepts common-mode voltages from 0.5 V to VDD−0.8 V; supports single-supply sensor biasing. |
| 4 | GND | Analog ground reference - must be star-connected to minimize crosstalk between channels and reduce THD+N. |
| 5 | IN+ B | Non-inverting input B - electrically isolated from Channel A; enables dual independent gain stages on one die. |
| 6 | IN− B | Inverting input B - matched offset and bias current to Channel A (max ΔVIO = 300 μV) for differential pair accuracy. |
| 7 | OUT B | Amplifier B output - identical drive capability to OUT A; supports stereo audio or redundant sensor paths. |
| 8 | VDD | Positive supply - accepts 4.5–16 V; internal regulation ensures consistent bandwidth and slew rate across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (ultra-low IB, 700 pA max) with bipolar output (high IOUT, low Zo = 0.25 Ω), eliminating trade-offs between input precision and output strength. |
| Single-Supply Input Range | 0.5 V to VDD−0.8 V - enables direct connection to 0–5 V or 0–12 V sensor outputs without level-shifting resistors or charge pumps. |
| Channel Shutdown Control | Dedicated SHDN pin per channel (not present on TLC072AIDR; confirmed absent per family table - only TLC070/73/75 include SHDN) - so this feature does not apply; TLC072AIDR has no shutdown function. |
| High PSRR & CMRR | 130 dB PSRR and 100 dB CMRR - rejects ripple from shared 12 V rails and common-mode noise in motor-control feedback loops. |
| Robust Capacitive Load Drive | Stable with up to 50 pF load capacitance - eliminates need for isolation resistors when driving ADC input capacitors or long cables. |
Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel general-purpose operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Lower bandwidth (5.5 MHz), lower output drive (±20 mA), but rail-to-rail input/output and lower input bias current (0.2 pA). | Better suited for ultra-high-impedance pH or ion-selective electrode interfaces where input leakage dominates error. | Select OPA2340UA when input bias current <1 pA is mandatory and output load ≤10 kΩ; avoid for 600 Ω audio or high-current actuator drivers. |
| LMV722MMX | Higher quiescent current (1.2 mA/channel), lower slew rate (1.5 V/μs), but smaller 8-pin VSSOP package and wider temp range (−40°C to 125°C). | Optimized for space-constrained portable instrumentation where board area is more critical than speed or drive strength. | Select LMV722MMX when footprint reduction outweighs need for 10 MHz bandwidth or ±55 mA drive; verify stability with 100 pF loads. |
Compared with OPA2340UA and LMV722MMX, TLC072AIDR uniquely balances 10 MHz bandwidth, ±55 mA output, and 7 nV/√Hz noise in a standard SOIC-8 - making it optimal for industrial and automotive signal chains demanding both speed and robustness without design compromises.

FAQ
What is the operating temperature range of the TLC072AIDR?
The TLC072AIDR is rated for operation from −40°C to +125°C, as indicated by the "I" suffix in the part number. This extended industrial temperature range is validated per TI's SLOS219F datasheet and supports deployment in under-hood automotive modules, factory-floor PLCs, and outdoor industrial enclosures without derating.
Does the TLC072AIDR have a shutdown pin?
No, the TLC072AIDR does not include a shutdown function. Per the family package table and pinout diagrams in the SLOS219F datasheet, only TLC070, TLC073, and TLC075 variants feature SHDN pins; TLC072 and TLC074 are non-shutdown dual and quad versions. Power management must be handled externally.
What is the maximum capacitive load the TLC072AIDR can drive stably?
The TLC072AIDR maintains stability with up to 50 pF of capacitive load at unity gain, as confirmed by phase margin measurements (≥32° at CL = 50 pF, RL = 10 kΩ) in the SLOS219F datasheet Figure 19–20. For loads >50 pF, a small series isolation resistor (10–50 Ω) is recommended at the output.
Can the TLC072AIDR operate from a 3.3 V supply?
No, the TLC072AIDR requires a minimum supply voltage of 4.5 V per the "Recommended Operating Conditions" table in SLOS219F. At 3.3 V, key parameters including bandwidth, slew rate, and output swing degrade outside specification - use TI's TLV2462 or OPA2333 for true 2.7–5.5 V operation.
Is the TLC072AIDR pin-compatible with the TL072CP?
Yes, the TLC072AIDR uses the same 8-pin SOIC (D) package and identical pinout as the TL072CP, enabling drop-in replacement in existing designs. However, note that TLC072AIDR offers 3× higher bandwidth (10 MHz vs 3 MHz), 2× faster slew rate, and improved input offset (2 mV max vs 10 mV max), requiring verification of loop stability in high-gain configurations.
