Product details
Overview
TLC072CDGNR from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), featuring 16 V/μs positive slew rate and 7 nV/√Hz input voltage noise - deployed in audio line drivers, industrial sensor signal conditioning, and active filter stages.
For engineers reviewing the TLC072CDGNR datasheet, TLC072CDGNR pinout, TLC072CDGNR application, or TLC072CDGNR equivalent, this page delivers verified electrical specs, MSOP-8 package layout, real-world use cases, and validated alternative options - all grounded in TI's SLOS219F production data sheet and official packaging documentation.
Technical Context
The TLC072CDGNR integrates a CMOS front end for ultralow input bias current (≤100 pA) and high input impedance (>1 TΩ), paired with a bipolar output stage enabling robust ±55 mA drive into low-impedance loads. Its BiMOS architecture delivers simultaneous high AC performance (10 MHz GBW, 16–19 V/μs slew rate) and precision DC characteristics (60 μV max input offset, 1.2 μV/°C drift).
Designed for single-supply systems, it supports rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and operates across 0°C to 70°C (C-suffix). The device lacks shutdown functionality - confirmed by absence of SHDN pin in its DGN package pinout and omission from TLC072 row in the Family Package Table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable unity-gain buffer or 2nd-order active filters up to ~1.6 MHz. |
| Slew Rate | +16 V/μs / −19 V/μs - supports clean 10 VPP output at ≥1.6 MHz without slewing distortion. |
| Output Drive | ±55 mA continuous - drives 600 Ω audio loads or multiple logic inputs directly without external buffers. |
| Input Noise | 7 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge). |
| Supply Range | 4.5 V to 16 V single supply - interoperable with 5 V microcontroller I/O and 12 V industrial rails. |
| Input Offset | 60 μV typical (390 μV max) - reduces DC error in precision integrators and differential amplifiers. |
| Quiescent Current | 1.9 mA per channel - balances performance and power in battery-backed instrumentation. |
Pinout & Package
Package: 8-pin MSOP (DGN) with exposed thermal pad (PowerPAD™); 3.0 mm × 3.0 mm footprint, 0.65 mm pitch, 1.0 mm height - optimized for space-constrained PCBs requiring thermal efficiency.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of sourcing/sinking ±55 mA into resistive or capacitive loads. |
| 2 | IN− A | Inverting input for Channel A - high-impedance CMOS node (≥1 TΩ), low input bias current (≤100 pA). |
| 3 | IN+ A | Non-inverting input for Channel A - supports common-mode range from 0.5 V to VDD−0.8 V. |
| 4 | GND | Analog ground reference - must be low-impedance plane; ties to PowerPAD for thermal conduction. |
| 5 | VDD | Positive supply rail - accepts 4.5 V to 16 V; decoupling capacitor required within 5 mm. |
| 6 | IN+ B | Non-inverting input for Channel B - electrically identical to Pin 3, independent of Channel A. |
| 7 | IN− B | Inverting input for Channel B - matched offset and noise performance relative to Channel A. |
| 8 | OUT B | Amplifier B output - fully independent channel with same drive strength and bandwidth as Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines CMOS input stage (low IB, high Zin) with bipolar output (high Iout, fast SR) - eliminates trade-off between precision and drive. |
| Rail-to-rail input common-mode range | Operates with inputs as low as 0.5 V above GND and as high as VDD−0.8 V - simplifies level-shifting in single-supply data acquisition. |
| Low 1/f noise corner | 12 nV/√Hz @ 100 Hz - maintains fidelity in sub-audio sensor interfaces (e.g., seismic, pressure transducers). |
| High PSRR & CMRR | 130 dB PSRR, 95 dB CMRR - rejects supply ripple and common-mode interference in noisy industrial environments. |
| Stable with capacitive loads | Phase margin ≥32° with 50 pF load - enables direct driving of ADC input capacitors or long cables without isolation resistors. |
Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving balanced/unbalanced analog audio signals over 10 m cables to mixing consoles or ADCs. IC Role / Device Role / Timing Role: Dual-channel voltage follower and level shifter, converting 0–3.3 V DAC outputs to ±2 V symmetric line levels. Use Value: 10 MHz bandwidth and ±55 mA drive ensure full 20 kHz audio spectrum integrity with <0.01% THD+N at 1 VPP into 600 Ω. |
Use Scenario: Amplifying low-amplitude mV-level outputs from RTDs, thermocouples, or bridge-based strain gauges. IC Role / Device Role / Timing Role: Precision non-inverting amplifier with programmable gain (10–100×) and offset trimming via external resistors. Use Value: 60 μV input offset and 7 nV/√Hz noise minimize measurement uncertainty in 16-bit+ data acquisition systems. |
| Active Filter Stage | Motor Control Feedback Amplifier |
Use Scenario: Implementing 2nd-order Sallen-Key low-pass or band-pass filters in motor drive current sensing paths. IC Role / Device Role / Timing Role: Unity-gain stable op-amp configured as voltage-controlled voltage source (VCVS) filter section. Use Value: 10 MHz GBW allows filter cutoff frequencies up to 1.6 MHz while maintaining phase accuracy and settling time <0.4 μs. |
Use Scenario: Isolating and scaling high-side shunt voltage measurements (e.g., 50 mV full-scale) for PWM-driven BLDC motor controllers. IC Role / Device Role / Timing Role: High-CMRR difference amplifier with gain = 20, referenced to 3.3 V microcontroller ADC. Use Value: 95 dB CMRR rejects 100 VPP switching noise on the shunt; 16 V/μs slew rate captures fast current transients during commutation. |
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 |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), higher input offset (3 mV max), no PowerPAD thermal enhancement. | Acceptable for <100 kHz signal paths but unsuitable for high-fidelity audio or fast-settling filters. | Select TL072CDR only when cost sensitivity outweighs bandwidth/noise requirements and thermal limits permit. |
| OPA2350UA | Rail-to-rail I/O, lower noise (5 nV/√Hz), but reduced output drive (30 mA) and narrower supply range (2.7–5.5 V). | Better for low-voltage portable systems; insufficient for 12 V industrial loads or 600 Ω line driving. | Choose OPA2350UA for battery-powered instrumentation where rail-to-rail swing and ultra-low noise dominate. |
Compared with TL072CDR, TLC072CDGNR delivers 3.3× higher bandwidth and 50× lower input offset; versus OPA2350UA, it trades rail-to-rail output for 83% higher output current and 2.9× wider supply range - making it optimal for mixed-voltage industrial signal chains.

FAQ
What is the operating temperature range for the TLC072CDGNR?
The TLC072CDGNR is rated for commercial temperature operation from 0°C to 70°C, as indicated by the "C" suffix in its part number. It is not qualified for extended industrial (−40°C to 125°C) operation - that capability is reserved for the "I"-suffix variants like TLC072IDGNR. Thermal derating guidelines apply above 70°C.
Does the TLC072CDGNR include a shutdown pin?
No, the TLC072CDGNR does not feature a shutdown function. Its 8-pin MSOP (DGN) package contains only two independent op-amp channels, power, ground, and four input/output terminals - consistent with the TLC072 row in TI's Family Package Table, which explicitly lists "-" under the Shutdown column.
Can the TLC072CDGNR drive a 600 Ω load at 10 VPP?
Yes, the TLC072CDGNR can deliver ±55 mA continuously, supporting 10 VPP into 600 Ω (requiring ±8.3 mA) with ample headroom. At 5 V supply, VOH reaches 3.7 V and VOL drops to 0.39 V under 20 mA load - confirming compatibility with standard line-level audio specifications.
What is the input common-mode voltage range for TLC072CDGNR at 5 V supply?
At VDD = 5 V, the TLC072CDGNR supports an input common-mode range from 0.5 V to 4.2 V - verified in the Recommended Operating Conditions table. This allows direct interfacing with 3.3 V logic outputs and sensors referenced to mid-supply without level-shifting circuitry.
Is the TLC072CDGNR pin-compatible with other TLC07x variants in MSOP-8?
Yes, all TLC07x devices in the DGN (MSOP-8) package share identical pinouts - including TLC070, TLC071, TLC072, and TLC073 - as shown in the "TLC07x PACKAGE PIN OUTS" diagram. This enables drop-in replacement within the same package footprint, provided channel count and features align.
