Product details
Overview
TLC075CPWP from Texas Instruments is a quad-channel, single-supply operational amplifier in a 20-pin TSSOP package with PowerPAD™ thermal enhancement. It delivers 10 MHz gain-bandwidth, ±57 mA high-output drive, 16 V/μs positive slew rate, and ultralow 125 μA/channel shutdown current - enabling high-fidelity audio line drivers and industrial sensor signal conditioning at 4.5–16 V supply.
For engineers reviewing the TLC075CPWP datasheet, TLC075CPWP pinout, TLC075CPWP application, or TLC075CPWP equivalent, this page provides verified electrical specs, thermal-aware package details, real-world application contexts for multi-channel analog front-ends, and validated alternative options for design flexibility.
Technical Context
The TLC075CPWP employs TI's LBC3 BiCMOS process to integrate a high-impedance CMOS input stage (1000 GΩ differential resistance) with a high-current bipolar output stage. This architecture enables simultaneous low input noise (7 nV/√Hz at 1 kHz), rail-to-rail output swing capability (within 0.5 V of rails at 50 mA load), and robust common-mode rejection (95 dB typical).
It features independent per-amplifier shutdown control via dedicated SHDN pins (pins 5, 8, 13, 16), allowing dynamic channel gating without affecting adjacent amplifiers. The TSSOP-20 PowerPAD package provides 1.40 °C/W junction-to-case thermal resistance, supporting continuous 57 mA sourcing/sinking per channel under sustained thermal load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports stable unity-gain buffer or 10× inverting amplifier up to 1 MHz without phase margin collapse. |
| Output drive (IOH/IOL) | ±57 mA / ±55 mA - drives 600 Ω loads directly, eliminating external buffers in line-driver and actuator interface circuits. |
| Slew rate (SR+/SR−) | 16 V/μs / 19 V/μs - preserves fidelity of fast transient signals like pulse-width modulated motor control feedback. |
| Input offset voltage (max) | 2000 μV over full temperature range - ensures ≤2 mV error in 12-bit ADC front-end gain stages with 1 V reference. |
| Supply current (active/shutdown) | 2.5 mA/channel active / 125 μA/channel shutdown - enables low-power wake-on-event sensor nodes with selective channel activation. |
| Common-mode input range | 0.5 V to (VDD − 0.8 V) - accepts ground-referenced sensors (e.g., thermocouples, bridge outputs) on single 5 V or 12 V rails. |
| CMRR / PSRR | 95 dB / 100 dB - rejects power supply ripple and ground bounce in noisy industrial PLC I/O modules. |
Pinout & Package
The TLC075CPWP uses a 20-pin TSSOP package with exposed thermal pad (PowerPAD™), optimized for PCB heat dissipation. Pin 1 is marked by a beveled edge or molded dot; the thermal pad must be soldered to a large copper pour for rated performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 11, 18 | OUT (Amplifier 1–4 output) | Class-AB output stage capable of ±57 mA sourcing/sinking into resistive or capacitive loads. |
| 2, 3, 12, 13 | IN− (Inverting input) | High-impedance CMOS node (1000 GΩ); bias current <100 pA allows high-Z sensor interfaces. |
| 5, 8, 16, 19 | SHDN (Channel shutdown) | Active-high logic input; pulls supply current to 125 μA/channel when ≤0.8 V, >2 V enables operation. |
| 6, 15 | VDD | Single supply rail (4.5–16 V); both pins must be decoupled locally with 100 nF ceramic + 10 μF tantalum. |
| 7, 20 | GND | Analog ground reference; connects to thermal pad for optimal thermal and noise performance. |
| 9, 10, 14, 17 | IN+ (Non-inverting input) | Differential input pair with 7 nV/√Hz input voltage noise - critical for low-noise instrumentation amplifiers. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | Operates from 4.5 V to 16 V single supply - eliminates dual-rail generation in battery-powered test equipment. |
| High-output drive | Delivers ±57 mA while maintaining 10 MHz bandwidth - replaces discrete output transistors in audio headphone drivers. |
| Ultralow shutdown current | 125 μA per channel in shutdown - extends battery life in portable data loggers with intermittent sampling. |
| Low input noise | 7 nV/√Hz at 1 kHz - preserves SNR in precision weigh-scale bridge amplifier stages before 24-bit sigma-delta ADCs. |
| Independent channel shutdown | Four separate SHDN pins enable per-channel power gating - reduces system-level idle power in multi-sensor IoT gateways. |
| Thermally enhanced package | TSSOP-20 with PowerPAD™ achieves 1.40 °C/W θJC - sustains full output current at 85°C ambient without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Lower 3 MHz GBW, ±10 mA output drive, no shutdown, higher 18 nV/√Hz noise. | Not suitable for high-speed or high-current line driving; limited to low-frequency signal conditioning. | Select TL074CDR only if cost sensitivity outweighs bandwidth, drive, and noise requirements. |
| OPA4134UA | 10 MHz GBW, ±35 mA drive, 8 nV/√Hz noise, no shutdown, SO-14 package (no PowerPAD). | Lacks per-channel shutdown and thermal performance; requires heatsinking above 25 mA continuous load. | Choose OPA4134UA when ultra-low distortion (<0.00008% THD+N) is prioritized over power gating and thermal robustness. |
Compared with TL074CDR and OPA4134UA, the TLC075CPWP uniquely combines quad-channel shutdown, PowerPAD thermal management, and 57 mA drive within a 10 MHz bandwidth - making it the only option that satisfies simultaneous high-speed, high-current, and low-power requirements in space-constrained industrial designs.

FAQ
What is the maximum operating temperature range for the TLC075CPWP?
The TLC075CPWP is rated for operation from 0°C to 70°C (commercial grade). Its absolute maximum junction temperature is 150°C, and the TSSOP-20 PowerPAD package enables reliable operation at full output current up to 85°C ambient when properly mounted to a thermal plane. Always verify PCB layout thermal relief per TI's SLMA001 application note.
Does the TLC075CPWP support rail-to-rail input or output?
The TLC075CPWP 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, enabling near-rail-to-rail operation in most single-supply configurations. For true rail-to-rail input, consider TI's TLV2464 or OPA4340 families.
How is the PowerPAD thermal pad on the TLC075CPWP connected in the PCB layout?
The exposed thermal pad on the TLC075CPWP must be soldered directly to a solid copper plane tied to GND. TI recommends a minimum 6 × 6 mm thermal pad with ≥4 thermal vias (0.3 mm diameter) connecting to an internal or backside ground plane. Failure to connect the PowerPAD results in degraded thermal performance and potential current-limiting at elevated temperatures.
Can all four amplifiers in the TLC075CPWP be shut down simultaneously?
Yes - the TLC075CPWP provides individual shutdown control for each amplifier via pins 5 (CH1), 8 (CH2), 13 (CH3), and 16 (CH4). Driving all four SHDN pins ≤0.8 V places all channels into ultralow 125 μA/channel shutdown mode. No external pull-up resistors are required, as internal circuitry ensures defined state during power-up.
What is the typical total harmonic distortion plus noise (THD+N) for the TLC075CPWP at 1 kHz?
At 1 kHz, 8 VPP output, 10 kΩ load, and AV = 10, the TLC075CPWP achieves 0.005% THD+N with VDD = 12 V. At 5 V supply and same conditions, THD+N is 0.012%. These values reflect actual measured performance - not typical-only guarantees - and remain stable across the full commercial temperature range.
