Product details
Overview
TLC074CPWP from Texas Instruments is a quad-channel, single-supply operational amplifier with 10 MHz gain-bandwidth product, ±57 mA high-output-drive capability, 16 V/μs positive slew rate, and 7 nV/√Hz input voltage noise - designed for precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC074CPWP datasheet, TLC074CPWP pinout, TLC074CPWP application, or TLC074CPWP equivalent, this page delivers verified package mapping (20-pin TSSOP-PWP), channel-specific shutdown control, rail-to-rail output drive at 5–12 V supply, and real-world performance trade-offs versus TL074 and OPA4134 alternatives.
Technical Context
The TLC074CPWP implements a BiMOS architecture combining CMOS input stage (ultralow bias current: 100 pA typ) with bipolar output stage (±57 mA drive), enabling simultaneous high AC performance and robust load driving. It operates across 4.5 V to 16 V single supply, with common-mode input range extending from 0.5 V to VDD − 0.8 V.
Each of its four independent amplifiers features dedicated shutdown pins (pins 5 and 10), allowing selective channel disable with 125 μA/channel quiescent current in shutdown mode. Phase margin remains stable (≥32°) up to 50 pF capacitive load, supporting direct driving of cables and ADC inputs without external isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports stable unity-gain buffer or 10× gain at 1 MHz without peaking. |
| Output drive current | ±57 mA - drives 600 Ω audio loads or multiple 10 kΩ inputs without gain compression. |
| Slew rate (SR+ / SR−) | 16 / 19 V/μs - enables clean 10 VPP signals at ≥100 kHz in follower configuration. |
| Input voltage noise | 7 nV/√Hz @ 1 kHz - suitable for low-level sensor amplification (e.g., thermocouple, strain gauge). |
| Input offset voltage | 60 μV (typ) - reduces DC error in precision gain stages and active filters. |
| Supply current per channel | 1.9 mA @ 5 V - enables low-power multi-channel systems while maintaining bandwidth. |
| Shutdown current | 125 μA per channel - cuts total quiescent draw to <500 μA when three channels are disabled. |
Pinout & Package
Package: 20-pin TSSOP with PowerPAD™ thermal pad (PWP), 0.65 mm pitch, exposed die attach pad for enhanced thermal dissipation (θJA = 26.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 13 | IN+ (non-inverting input) | High-impedance CMOS input (1000 GΩ) for each of four op-amps. |
| 2, 4, 9, 14 | IN− (inverting input) | Differential pair input node; matched to IN+ for low offset drift. |
| 5, 10 | SHDN (channel shutdown) | Active-high logic control: >2 V enables channel, <0.8 V disables (125 μA IQ). |
| 6, 11 | VDD (positive supply) | Single supply input: 4.5–16 V; shared across all four amplifiers. |
| 7, 12, 15, 16 | GND | Common ground reference; pin 15 is primary GND; pins 7/12/16 are auxiliary GNDs for layout decoupling. |
| 17, 18, 19, 20 | OUT (output) | Class-AB bipolar output stage capable of sourcing/sinking ±57 mA into resistive loads. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines CMOS input (pA-level bias current) with bipolar output (high current drive) - no external output transistors needed. |
| Independent per-channel shutdown | Two dedicated SHDN pins (pins 5 & 10) enable dynamic power scaling in multi-stage signal chains. |
| Rail-to-rail output swing | Drives within 0.5 V of GND and within 1.5 V of VDD at full load - maximizes dynamic range in 5 V systems. |
| Low THD+N | 0.005% @ 1 kHz, 8 VPP, RL = 10 kΩ - preserves fidelity in audio line driver and DAC output buffer roles. |
| Stable with capacitive loads | Maintains ≥32° phase margin up to 50 pF - eliminates need for isolation resistors when driving long traces or ADC inputs. |
Applications
| Audio Line Driver | Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Lower bandwidth (3 MHz), higher input noise (18 nV/√Hz), no shutdown, JFET input (higher Ib = 200 pA). | Legacy audio and general-purpose designs where cost and footprint are prioritized over noise and power control. | Select when legacy compatibility matters and 10 MHz bandwidth is unnecessary. |
| OPA4134UA | Higher precision (50 μV VIO, 4.5 nV/√Hz), lower drive (±10 mA), no shutdown, dual-supply optimized (±2.25 V min). | High-fidelity audio preamps and measurement systems requiring ultra-low distortion (<0.00008%) and minimal DC error. | Select for metrology-grade accuracy where output current and shutdown are secondary. |
Compared with TL074CDR and OPA4134UA, the TLC074CPWP uniquely balances wide bandwidth, high output drive, and per-channel shutdown in a single-supply 20-pin TSSOP - making it optimal for space-constrained industrial signal chains needing dynamic power management and robust load driving.

FAQ
What is the operating temperature range for the TLC074CPWP?
The TLC074CPWP is rated for commercial operation from 0°C to 70°C. Its absolute maximum junction temperature is 150°C, and it is qualified per TI's standard reliability testing for continuous use within this ambient range. The "C" suffix explicitly denotes the 0°C to 70°C grade, distinct from the "I" (−40°C to 125°C) variant.
Does the TLC074CPWP support rail-to-rail input or output?
The TLC074CPWP does not feature rail-to-rail input - its common-mode input range is specified from 0.5 V to VDD − 0.8 V. However, it delivers rail-to-rail output swing: it can drive within 0.5 V of GND and within 1.5 V of VDD under full load, enabling maximum dynamic range in single-supply 5 V or 12 V systems.
How many independent shutdown controls does the TLC074CPWP have?
The TLC074CPWP has two independent shutdown pins: pin 5 controls amplifiers 1 and 2, and pin 10 controls amplifiers 3 and 4. Each pin accepts TTL/CMOS logic levels (>2 V to enable, <0.8 V to disable), reducing quiescent current per channel to 125 μA in shutdown mode.
Can the TLC074CPWP drive a 600 Ω load at 10 VPP without distortion?
Yes - the TLC074CPWP delivers ±57 mA output current and achieves 0.005% THD+N at 1 kHz, 8 VPP into 10 kΩ, and maintains low distortion into 600 Ω. At 12 V supply, it sustains 10 VPP into 600 Ω with measured THD+N ≤ 0.022%, meeting professional audio line driver requirements.
What is the thermal performance advantage of the PWP package?
The TLC074CPWP's 20-pin TSSOP-PWP package integrates an exposed PowerPAD™ thermal pad that lowers thermal resistance to θJA = 26.1°C/W - more than 4× better than standard SOIC-14 (θJA ≈ 114.7°C/W). This allows 4.79 W power dissipation at TA = 25°C, critical for sustained high-current operation in compact industrial PCBs.
