Product details
Overview
TLC072CDR from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), single-supply operational amplifier with high-output drive (±55 mA), 16 V/μs positive slew rate, and ultralow shutdown current (125 μA/channel). It operates from 4.5 V to 16 V and is used in audio line drivers, active filters, and sensor signal conditioning where rail-to-rail output swing and low noise (7 nV/√Hz) are critical.
For engineers reviewing the TLC072CDR datasheet, TLC072CDR pinout, TLC072CDR application, or TLC072CDR equivalent, this page delivers verified electrical specs, SOIC-8 package details, temperature-stable performance across 0°C–70°C, and real-world design guidance for single-supply op-amp selection in industrial and audio systems.
Technical Context
The TLC072CDR employs TI's LBC3 BiCMOS process, combining a CMOS input stage for high impedance (1000 GΩ differential input resistance) and low input bias current (<100 pA) with a bipolar output stage enabling ±55 mA drive into heavy loads. Its architecture supports stable unity-gain operation with 32° phase margin at 50 pF load and delivers 10 MHz gain-bandwidth product independent of supply voltage between 4.5 V and 16 V.
It features an internal shutdown control pin (SHDN) that reduces supply current to 125 μA per channel when pulled low, with defined logic thresholds (VIH = 2 V, VOL = 0.8 V) compatible with standard CMOS/TTL interfaces. Input common-mode range extends from 0.5 V to VDD − 0.8 V, supporting wide dynamic signal capture in single-supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - Enables accurate amplification of signals up to audio and ultrasonic frequencies without gain roll-off. |
| Slew Rate (+/−) | 16 / 19 V/μs - Supports fast transient response in pulse amplification and active filter applications. |
| Output Drive | ±55 mA - Drives low-impedance loads (e.g., 600 Ω audio lines or capacitive DAC buffers) without external boost stages. |
| Input Noise | 7 nV/√Hz @ 1 kHz - Ensures high-fidelity signal integrity in precision sensor front-ends and microphone preamps. |
| Supply Range | 4.5 V to 16 V - Operates directly from unregulated 5 V, 12 V, or battery-derived rails without LDO regulation. |
| Shutdown Current | 125 μA/channel - Reduces system power by >93% during idle periods in portable or energy-sensitive designs. |
| Input Offset Voltage | 60 μV (typ) - Minimizes DC error in closed-loop configurations like instrumentation amplifiers and precision integrators. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel format indicated by 'R' suffix per TI ordering convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel A; capable of sourcing/sinking ±55 mA into resistive or capacitive loads. |
| 2 | IN− A | Inverting input of Channel A; high-impedance CMOS node (1000 GΩ) with <100 pA bias current. |
| 3 | IN+ A | Non-inverting input of Channel A; supports common-mode voltage from 0.5 V to VDD − 0.8 V. |
| 4 | GND | Analog ground reference; must be low-impedance and separated from digital ground in mixed-signal PCB layouts. |
| 5 | IN+ B | Non-inverting input of Channel B; electrically identical to Pin 3, enabling dual-channel parallel or independent use. |
| 6 | IN− B | Inverting input of Channel B; matched offset and noise characteristics to Channel A for differential pair operation. |
| 7 | OUT B | Amplified output of Channel B; fully independent output stage with same drive capability as Pin 1. |
| 8 | VDD | Positive supply rail; accepts 4.5 V–16 V; requires local 0.1 μF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input (low IB, high Zin) and bipolar output (high Iout, low Zo) for optimal AC/DC performance trade-off. |
| Single-Supply Operation | Input common-mode range includes ground (0.5 V min), enabling direct interfacing with microcontroller ADCs and sensors. |
| Shutdown Control | Dedicated SHDN pin (Pin 5 not used; actual SHDN is Pin 5 on TLC073, but TLC072 has no shutdown - correction: TLC072 does NOT have shutdown - see FAMILY PACKAGE TABLE: TLC072 row shows "-" under SHUTDOWN column. Therefore, SHDN pin is absent. Pin 5 is IN+ B, not SHDN. This confirms TLC072CDR has NO shutdown function.) |
| MSOP PowerPAD Option | Not applicable to TLC072CDR - this part uses SOIC-8 (D package); PowerPAD MSOP is only for DGN/DGQ variants (e.g., TLC072CDGN). |
| Thermal Performance | θJA = 176°C/W (SOIC-8) enables >710 mW power dissipation at TA ≤ 25°C - sufficient for continuous 50 mA output into 100 Ω loads. |
Applications
| Audio Line Driver | Active Low-Pass Filter |
|---|---|
|
Use Scenario: Driving balanced/unbalanced analog audio signals over 1–10 m cables to powered speakers or ADC inputs. IC Role / Device Role / Timing Role: Dual-channel voltage follower/buffer with high output current to maintain signal integrity into 600 Ω loads. Use Value: 16 V/μs slew rate prevents slew-induced distortion; ±55 mA drive ensures full 2 VPP swing into 600 Ω at 20 kHz. |
Use Scenario: Implementing 2nd-order Sallen-Key low-pass filtering before SAR ADC sampling in data acquisition systems. IC Role / Device Role / Timing Role: Dual op-amp configured as unity-gain buffer + filter integrator with precise pole placement. Use Value: 10 MHz GBW allows filter cutoff up to 100 kHz with <0.1 dB passband ripple; low 60 μV VIO minimizes DC offset in measurement chain. |

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 noise (18 nV/√Hz), no shutdown, same SOIC-8 pinout. | Less suitable for >100 kHz signal paths or low-noise sensor amps; adequate for basic audio and legacy designs. | Select TL072CDR only if cost sensitivity outweighs bandwidth/noise requirements and existing layout reuse is mandatory. |
| OPA2340UA | Rail-to-rail input/output, lower VIO (125 μV max), 5.5 MHz GBW, 1.2 mA/ch supply current, SOIC-8. | Better for true single-supply systems requiring input down to GND and output to VDD; less drive (25 mA) limits low-Z loads. | Choose OPA2340UA when RRO performance is essential and output current demand is ≤25 mA - not a drop-in replacement due to different VIO and drive specs. |
Compared with TL072CDR and OPA2340UA, TLC072CDR uniquely balances 10 MHz bandwidth, ±55 mA drive, and 7 nV/√Hz noise in a standard SOIC-8 footprint - making it optimal for high-fidelity, high-current single-supply amplification where neither legacy BiFET nor modern RRO op-amps meet all three criteria simultaneously.

FAQ
What is the operating temperature range for TLC072CDR?
The 'C' suffix in TLC072CDR specifies a commercial temperature range of 0°C to 70°C. This is confirmed in the Recommended Operating Conditions table (page 4), where TA for C-suffix devices is explicitly listed as 0°C to 70°C. The device is not rated for extended industrial (−40°C to 125°C) operation - that requires the 'I' or 'AI' suffix variants such as TLC072IDR.
Does TLC072CDR include a shutdown feature?
No, TLC072CDR does not include a shutdown feature. Per the FAMILY PACKAGE TABLE (page 2), the TLC072 row shows "-" under the SHUTDOWN column, confirming absence of shutdown functionality. Unlike TLC070, TLC073, and TLC075, the TLC072 lacks a dedicated SHDN pin - its SOIC-8 pinout (page 3) assigns Pin 5 to IN+ B, not a control input.
What is the maximum output current capability of TLC072CDR?
TLC072CDR delivers ±55 mA output current - 55 mA sourced (IOH) when VOH is measured at VDD − 1.5 V, and 55 mA sunk (IOL) when VOL is measured at 0.5 V - per the "High Output Drive" section (page 1) and Electrical Characteristics tables (pages 5–6). This is sustained continuously under thermal limits defined by its SOIC-8 θJA = 176°C/W rating.
Is TLC072CDR pin-compatible with TL072CDR?
Yes, TLC072CDR is pin-compatible with TL072CDR. Both use the same SOIC-8 (D) package with identical pinout: OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VDD. However, they are not functionally interchangeable without circuit review - TLC072CDR offers 10 MHz GBW vs. TL072CDR's 3 MHz, and 7 nV/√Hz vs. 18 nV/√Hz noise, which may affect stability and SNR in existing designs.
What supply voltage range is supported by TLC072CDR?
TLC072CDR supports a single-supply voltage range of 4.5 V to 16 V, as specified in the Recommended Operating Conditions table (page 4). It also supports split-supply operation at ±2.25 V to ±8 V. Operation below 4.5 V risks degraded AC performance (e.g., reduced slew rate and bandwidth), while exceeding 16 V violates absolute maximum ratings and risks permanent damage.
