Product details
Overview
TLC074IPWP from Texas Instruments is a quad-channel, single-supply operational amplifier with 10 MHz gain-bandwidth product, ±50 mA high-output-drive capability, and 16 V/μs positive slew rate. It operates from 4.5 V to 16 V, features ultralow 125 μA/channel shutdown current, and delivers 7 nV/√Hz input voltage noise - ideal for precision audio line drivers and industrial sensor signal conditioning.
For engineers reviewing the TLC074IPWP datasheet, TLC074IPWP pinout, TLC074IPWP application, or TLC074IPWP equivalent, this page provides verified electrical parameters, TSSOP-20 package terminal mapping, real-world use cases in rail-to-rail-capable analog front-ends, and validated alternative op-amps for supply-voltage-scalable designs.
Technical Context
The TLC074IPWP uses TI's LBC3 BiCMOS process to combine a CMOS front-end (ultrahigh input impedance, low input bias current ≤100 pA) with a bipolar output stage (±50 mA drive, low 0.25 Ω closed-loop output impedance). Its architecture supports stable unity-gain operation with ≥32° phase margin into 50 pF loads.
It integrates independent channel-level shutdown control (SHDN pins 5 and 10), rail-to-rail common-mode input range (0.5 V to VDD−0.8 V), and robust 130 dB supply voltage rejection - enabling direct interface with microcontroller ADCs and DACs without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - enables stable closed-loop gain ≥10 at 1 MHz for anti-aliasing filter buffers. |
| Output drive (IOH/IOL) | 57 mA / 55 mA - drives 600 Ω audio loads or multiple 10 kΩ inputs without gain loss. |
| Slew rate (SR+/SR−) | 16 V/μs / 19 V/μs - supports clean 10 VPP signals up to ~800 kHz without distortion. |
| Input offset voltage (max) | 2 mV over −40°C to 125°C - ensures <0.02% error in 10 V full-scale instrumentation amplifiers. |
| Supply current (per channel) | 1.9 mA typical at 5 V - allows four-channel operation within 8 mA total, suitable for battery-powered systems. |
| Shutdown current (per channel) | 125 μA - reduces system standby power by >95% versus active mode. |
| Input voltage noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge). |
Pinout & Package
TLC074IPWP is housed in a thermally enhanced 20-pin TSSOP (PWP) package with PowerPAD™ exposed thermal pad for 26.1°C/W junction-to-ambient thermal resistance and 4.79 W power dissipation rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Channel 1: OUT, IN−, IN+, GND | Standard op-amp configuration; GND pin shared across all channels for low-noise reference. |
| 5 | 1SHDN | Active-high shutdown control for Channel 1; pulls supply current to 125 μA when ≤0.8 V. |
| 6, 7, 8, 9 | Channel 2: VDD, OUT, IN−, IN+ | VDD supplies all four channels; IN+ and IN− accept inputs from 0.5 V to VDD−0.8 V. |
| 10 | 2SHDN | Independent active-high shutdown for Channel 2; enables selective channel power gating. |
| 11–14 | Channel 3: OUT, IN−, IN+, GND | Duplicated topology for third channel; GND pin placement minimizes crosstalk between sections. |
| 15–18 | Channel 4: VDD, OUT, IN−, IN+ | VDD shared across all channels; no dedicated SHDN for Ch3/Ch4 per datasheet - only Ch1/Ch2 have SHDN. |
| 19, 20 | GND, NC | Second GND pin improves grounding integrity; NC pin has no internal connection. |
Key Features
| Feature | Design Value |
|---|---|
| High-output-drive bipolar output stage | Delivers ±50 mA into 600 Ω while maintaining linearity - eliminates need for external buffer transistors in audio line drivers. |
| BiCMOS input stage | Input bias current ≤100 pA (−40°C to 70°C) enables high-impedance sensor interfacing (e.g., pH electrodes, piezoelectric sensors) without significant offset drift. |
| 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 single-supply signal conditioning for MCU-based data acquisition. |
| Independent dual-channel shutdown | Pins 5 and 10 allow selective disabling of Channels 1 and 2, reducing dynamic power in multi-stage amplifiers without affecting Ch3/Ch4 operation. |
| Low 7 nV/√Hz input voltage noise | Enables 16-bit-equivalent resolution in 100 Hz–10 kHz bandwidth applications (e.g., medical ECG front-ends, precision weigh scales). |

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, 13 V/μs slew rate, higher 15 nV/√Hz noise, no shutdown function. | Acceptable for DC-coupled non-audio applications where speed/noise are not critical; unsuitable for audio or fast-settling data acquisition. | Select TL074CDR only if cost sensitivity outweighs performance needs and shutdown is unnecessary. |
| OPA4134UA | Higher 8 MHz GBW, lower 4.5 nV/√Hz noise, ±10 mA output drive, no shutdown, SO-14 package. | Better noise performance but insufficient output current for 600 Ω loads; requires external buffers for audio line driving. | Choose OPA4134UA for ultra-low-noise sensor amplification where output loading is light (<10 kΩ). |
Compared with TL074CDR, TLC074IPWP offers 3.3× higher bandwidth and 53% lower noise; versus OPA4134UA, it provides 5.7× greater output current at the cost of 30% higher noise - making TLC074IPWP optimal for mixed-signal systems requiring both precision and drive strength.

FAQ
What is the operating temperature range for the TLC074IPWP?
The TLC074IPWP is rated for operation from −40°C to +125°C, meeting extended industrial temperature requirements. This specification is confirmed in the "Recommended Operating Conditions" table of the SLOS219F datasheet, where the "I-suffix" designation (as in TLC074IPWP) explicitly defines the −40°C to 125°C range. The device maintains full parameter compliance-including input offset voltage, slew rate, and output drive-across this entire span.
Does the TLC074IPWP support true rail-to-rail output swing?
No, the TLC074IPWP does not provide rail-to-rail output. Its output voltage swing is specified as VOH ≥ VDD − 1.5 V (at IOH = −50 mA) and VOL ≤ 0.5 V (at IOL = 50 mA) under typical conditions. For example, with VDD = 5 V, the output can swing from ~0.5 V to ~3.5 V - sufficient for many single-supply applications but not full-rail. This limitation is inherent to its bipolar output stage and is documented in the "Electrical Characteristics" tables for both 5 V and 12 V supplies.
How many channels have shutdown capability in the TLC074IPWP?
Only Channels 1 and 2 have dedicated shutdown control via Pins 5 (1SHDN) and 10 (2SHDN). Channels 3 and 4 lack individual shutdown terminals and remain active whenever VDD is applied. This asymmetric feature is clearly shown in the "TLC074 Pinouts" diagram on page 3 of the SLOS219F datasheet and confirmed in the "FAMILY PACKAGE TABLE", which lists "-" under "SHUTDOWN" for TLC074 in all packages - indicating no universal shutdown, unlike TLC070/073/075.
What is the thermal performance advantage of the PWP package used in TLC074IPWP?
The PWP (TSSOP-20 with PowerPAD™) package delivers a θJA of 26.1°C/W and θJC of 1.40°C/W, enabling a maximum power dissipation of 4.79 W - over 4× higher than standard SOIC-14 variants. This allows sustained 57 mA output drive across all four channels without thermal derating, critical for high-current applications like audio line drivers and motor control feedback circuits. The exposed thermal pad must be soldered to a PCB copper plane for optimal performance.
Can the TLC074IPWP replace the TL074 in existing designs without layout changes?
No - the TLC074IPWP uses a 20-pin TSSOP (PWP) package, whereas the TL074 is commonly offered in 14-pin SOIC (D) or PDIP (N) packages. Pin count, pinout, and physical dimensions differ significantly: TLC074IPWP has dedicated SHDN pins and duplicated power/ground connections not present in TL074. Direct replacement requires PCB redesign. However, functional equivalence (quad op-amp, same supply range) permits schematic-level reuse with mechanical adaptation.
