Product details
Overview
TLC074AIPWP 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, 7 nV/√Hz input voltage noise, and 4.5 V to 16 V supply range - used in precision audio line drivers, industrial sensor signal conditioning, and high-current analog output stages.
For engineers reviewing the TLC074AIPWP datasheet, TLC074AIPWP pinout, TLC074AIPWP application, or TLC074AIPWP equivalent, this page delivers verified electrical specs, TSSOP-20 package layout, real-world use cases, and two validated alternative op-amps for design flexibility under wide temperature (−40°C to 125°C) and single-rail conditions.
Technical Context
The TLC074AIPWP employs TI's patented LBC3 BiCMOS process, integrating a low-noise CMOS front end (1000 GΩ differential input resistance, 7 nV/√Hz noise) with a high-drive bipolar output stage capable of sourcing/sinking ±50 mA into loads. Its rail-to-rail input common-mode range (0.5 V to VDD − 0.8 V) and shutdown mode (125 μA/channel) support low-power, high-fidelity analog signal paths.
It features four independent amplifiers in one package, each with dedicated shutdown control (pins 5 and 10), enabling channel-level power management. The device maintains stability with capacitive loads up to 100 pF and achieves >32° phase margin at 10 kΩ/50 pF, making it suitable for driving cables, ADC drivers, and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports stable unity-gain operation up to 10 MHz; enables fast settling in data acquisition front ends. |
| Output drive current | ±57 mA - drives low-impedance loads (e.g., 600 Ω audio lines, relay coils) without external buffers. |
| Slew rate | 16 V/μs (SR+) / 19 V/μs (SR−) - preserves fidelity of fast transient signals like pulse-width modulated analog outputs. |
| Input voltage noise | 7 nV/√Hz @ 1 kHz - critical for low-level sensor amplification (e.g., thermocouples, strain gauges) where noise dominates SNR. |
| Supply voltage range | 4.5 V to 16 V single supply - operates directly from 5 V or 12 V rails without dual supplies, simplifying power architecture. |
| Input offset voltage (max) | 2000 μV over full temperature range - ensures DC accuracy in closed-loop configurations with moderate gain (e.g., 10–100×). |
| Shutdown current | 125 μA per channel - reduces system standby power by >93% vs active mode (1.9 mA/channel), ideal for battery-powered instrumentation. |
Pinout & Package
TLC074AIPWP uses a 20-pin TSSOP (Thin Shrink Small Outline Package) with exposed thermal pad (PowerPAD™), optimized for thermal dissipation (θJA = 26.1°C/W) and board space efficiency in high-density analog layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 12, 14 | IN− (inverting input) | Differential inputs for channels 1–4; high-impedance CMOS node (1000 GΩ) minimizes loading on preceding stages. |
| 2, 4, 11, 13 | IN+ (non-inverting input) | Accepts common-mode voltages from 0.5 V to VDD − 0.8 V - supports single-supply sensing near ground or rail. |
| 5, 10 | SHDN (shutdown control) | Active-high logic input per pair (pins 5→Ch1/Ch2; pins 10→Ch3/Ch4); pulls supply current to 125 μA/channel when low. |
| 6, 7, 15, 16 | OUT (output) | Class-AB bipolar output stage delivers ±57 mA; capable of driving 600 Ω loads to ±3.5 V at 5 V supply. |
| 8 | GND | Analog ground reference; tied to PowerPAD for optimal thermal and noise performance. |
| 9, 17 | VDD | Single positive supply input (4.5–16 V); dual VDD pins reduce IR drop and improve PSRR (>80 dB). |
| 18–20, NC | No internal connection | Unused pins; must be left floating or grounded per layout guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Wide bandwidth + high drive | 10 MHz GBW with ±57 mA output enables simultaneous speed and power - replaces discrete buffer + op-amp combos in audio and actuator interfaces. |
| Ultra-low noise front end | 7 nV/√Hz input voltage noise at 1 kHz allows clean amplification of microvolt-level sensor signals without added filtering overhead. |
| Robust single-supply operation | Rail-to-rail input (0.5 V to VDD − 0.8 V) and output swing to within 0.5 V of rails simplify level-shifting in 5 V/12 V systems. |
| Channel-selectable shutdown | Independent SHDN pins (5 and 10) allow dynamic power gating of channel pairs - essential for multi-range instrument front ends. |
| High PSRR and CMRR | 100 dB supply rejection and 95 dB common-mode rejection minimize error from noisy rails or unbalanced sensor bridges. |

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 bandwidth (3 MHz), higher VIO (10 mV max), no shutdown, 16 V/μs slew rate limited to ±10 V supply. | Cost-sensitive general-purpose designs without low-noise or power-gating requirements. | Choose TL074CDR only if noise, drive strength, and shutdown are non-critical; not suitable for 5 V single-supply or battery operation. |
| OPA4134UA | Lower noise (6.5 nV/√Hz), lower IBIAS (1 pA), but lower output drive (±25 mA), no shutdown, SOIC-14 package only. | Ultra-low-noise audio preamps where output current <25 mA suffices and PCB area permits larger SOIC. | Choose OPA4134UA when sub-7 nV/√Hz noise and femtoampere bias are mandatory; avoid when driving 600 Ω or requiring channel shutdown. |
Compared with TL074CDR and OPA4134UA, TLC074AIPWP uniquely combines 10 MHz bandwidth, ±57 mA drive, integrated shutdown, and TSSOP-20 thermal performance - making it the only option among the three that supports high-fidelity, high-current, low-power, and space-constrained analog subsystems across −40°C to 125°C.

FAQ
What is the operating temperature range for TLC074AIPWP?
The TLC074AIPWP is rated for −40°C to +125°C, confirmed by TI's SLOS219F datasheet Section 4 (Recommended Operating Conditions). This extended industrial range enables deployment in harsh environments such as motor control cabinets, automotive engine compartments, and outdoor instrumentation enclosures where ambient temperatures exceed standard commercial limits.
Does TLC074AIPWP support true rail-to-rail input operation?
TLC074AIPWP supports a common-mode input voltage range from 0.5 V to VDD − 0.8 V - not full rail-to-rail, but sufficient to accommodate signals near ground (e.g., 0.5 V above GND) and within 0.8 V of the positive rail. This is explicitly specified in the "Common-mode input voltage" parameter (VICR) across all test conditions in the datasheet.
How does the shutdown function work on TLC074AIPWP?
TLC074AIPWP has two independent shutdown pins: pin 5 controls channels 1 and 2, and pin 10 controls channels 3 and 4. When pulled ≤0.8 V (logic low), each pair enters ultralow-power mode drawing just 125 μA per channel. This behavior is documented in the "Supply current in shutdown mode" specification and timing diagrams for t(on)/t(off) in the datasheet.
Can TLC074AIPWP drive a 600 Ω load at 5 V supply?
Yes - TLC074AIPWP delivers ±57 mA output current, enabling it to swing ±3.5 V into a 600 Ω load at VDD = 5 V (per VOH/VOL specs in Section 5, VDD = 5 V table). This meets professional audio line-driving standards and eliminates need for external buffer transistors in most implementations.
What is the thermal performance advantage of the TSSOP-20 PowerPAD package used by TLC074AIPWP?
The TLC074AIPWP's TSSOP-20 PowerPAD package achieves θJA = 26.1°C/W - significantly lower than standard SOIC-14 (θJA ≈ 122°C/W) or PDIP-14 (θJA ≈ 78°C/W). This allows continuous 4.79 W power dissipation (per Dissipation Rating Table), supporting high-output-drive operation without thermal derating in compact industrial PCB layouts.
