Product details
Overview
TLC075IDR from Texas Instruments is a quad-channel, single-supply operational amplifier with 10 MHz gain-bandwidth product, ±50 mA high-output-drive capability, 16 V/μs positive slew rate, and ultralow 125 μA/channel shutdown current. It operates from 4.5 V to 16 V across −40°C to 125°C and is used in precision audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring rail-to-rail output swing and robust load driving.
For engineers reviewing the TLC075IDR datasheet, TLC075IDR pinout, TLC075IDR application, or TLC075IDR equivalent, this page delivers verified electrical specs, thermal performance data, shutdown timing (1.3 μs turn-off), noise floor (7 nV/√Hz at 1 kHz), and real-world load-driving behavior under 5 V and 12 V supplies - critical for analog front-end design validation and BOM optimization.
Technical Context
The TLC075IDR implements TI's patented LBC3 BiCMOS process, combining a low-noise CMOS input stage (1000 GΩ differential input resistance, 7 nV/√Hz input voltage noise) with a high-current bipolar output stage capable of sourcing 57 mA and sinking 55 mA. Its architecture supports stable unity-gain operation with 37° phase margin into 50 pF capacitive loads at 12 V supply.
It features independent per-amplifier shutdown control via dedicated SHDN pins (pins 5 and 13), enabling dynamic power management in multi-channel systems. The device maintains 80 dB CMRR and 100 dB PSRR over frequency up to 100 kHz, ensuring immunity to supply and common-mode disturbances in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - enables stable closed-loop operation up to 10× gain at 1 MHz, suitable for active filters and wideband instrumentation. |
| Output drive (IOH/IOL) | 57 mA / 55 mA - drives 600 Ω audio loads or multiple logic inputs without external buffers. |
| Slew rate (SR+/SR−) | 16 V/μs / 19 V/μs - supports fast transient response in pulse amplification and DAC output buffering. |
| Input offset voltage (max) | 2000 μV - ensures ≤2 mV error in 12-bit ADC reference buffers at room temperature. |
| Supply current (active/shutdown) | 2.5 mA/channel / 250 μA/channel - reduces total system quiescent power by >90% during idle cycles. |
| Input noise voltage | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge). |
| Common-mode input range | 0.5 V to VDD−0.8 V - allows direct interfacing with 0–5 V or 0–12 V sensor outputs without level-shifting. |
Pinout & Package
Package: 16-pin SOIC (D package), 7.5 mm × 10.3 mm footprint, standard JEDEC MS-012AC, rated for −40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 10, 13 | SHDN (x4) | Individual channel enable/disable: logic high (>2 V) activates amplifier; low (<0.8 V) places channel in 125 μA shutdown mode. |
| 2, 6, 9, 12 | IN− (x4) | Inverting input terminals - high-impedance CMOS node (1000 GΩ) minimizing loading on preceding stages. |
| 3, 7, 11, 14 | IN+ (x4) | Non-inverting input terminals - matched to IN− for <2000 μV input offset and 80 dB CMRR. |
| 4, 15 | GND | Analog ground reference - dual ground pins reduce ground bounce in multi-channel switching applications. |
| 8, 16 | VDD | Positive supply rail - accepts 4.5 V to 16 V; internal regulation ensures stable biasing across full voltage range. |
| 1OUT, 2OUT, 3OUT, 4OUT | OUT (pins 1, 6, 9, 12) | Class-AB output stage - delivers ±50 mA into resistive loads and remains stable with ≥50 pF capacitive loads. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 4.5 V to 16 V single supply - eliminates need for split rails in battery-powered or 12 V automotive systems. |
| High-output-drive capability | ±50 mA per channel - directly drives relays, LEDs, or transmission lines without external transistors. |
| Ultralow-power shutdown | 125 μA/channel - enables microamp-level sleep modes in portable instrumentation and IoT edge nodes. |
| Low input voltage noise | 7 nV/√Hz at 1 kHz - critical for preserving resolution in 16-bit+ data acquisition front ends. |
| Robust capacitive-load drive | Stable with ≥50 pF - simplifies PCB layout for LCD bias, piezo driver, or long-cable interfaces. |
| Extended temperature range | −40°C to 125°C - qualified for under-hood automotive, industrial motor control, and outdoor infrastructure. |

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 input offset (10 mV max), no shutdown function, 2.5 mA/channel supply current. | Limited to low-speed signal conditioning where power and precision are secondary to cost. | Choose TL074CDR only when legacy design reuse or ultra-low BOM cost outweighs need for speed, drive strength, and power management. |
| OPA4134UA | Lower noise (8 nV/√Hz), lower supply current (4 mA/channel), no shutdown, 4 MHz GBW, ±10 mA output drive. | Better suited for ultra-low-noise audio preamps but cannot drive heavy loads or support dynamic power scaling. | Select OPA4134UA for high-fidelity audio where noise dominates over drive capability; avoid for industrial actuator interfaces. |
Compared with TL074CDR and OPA4134UA, the TLC075IDR uniquely balances wide bandwidth (10 MHz), high output drive (±50 mA), and ultralow shutdown current (125 μA) - making it the only option among the three that meets simultaneous requirements for fast, high-current, and energy-efficient analog signal routing.

FAQ
What is the maximum capacitive load the TLC075IDR can drive while maintaining stability?
The TLC075IDR maintains phase margin ≥37° with up to 50 pF capacitive load at 12 V supply and 10 kΩ resistive load, as confirmed in Figure 20 of the SLOS219F datasheet. For loads >50 pF, external series resistance (≥20 Ω) at the output is recommended to preserve stability without degrading step response.
Does the TLC075IDR support true rail-to-rail input or output operation?
The TLC075IDR does not provide rail-to-rail input: its common-mode input range is specified from 0.5 V to VDD−0.8 V. However, its output swings within 0.5 V of GND and 1.5 V of VDD under 50 mA load, delivering near rail-to-rail performance suitable for most single-supply applications including 0–5 V and 0–12 V systems.
How does the shutdown feature behave across temperature for the TLC075IDR?
The TLC075IDR shutdown threshold is defined as VIH ≥2 V and VOL ≤0.8 V, with shutdown supply current remaining ≤250 μA across −40°C to 125°C (per Table 6, SLOS219F). Turn-off time increases from 1.3 μs at 25°C to 2.5 μs at 125°C, as shown in Figure 10 operating characteristics.
Can the TLC075IDR be used with a 3.3 V supply?
No - the TLC075IDR has a minimum supply voltage of 4.5 V per Absolute Maximum Ratings and Recommended Operating Conditions tables. Operation below 4.5 V risks undefined behavior, reduced output swing, and failure to meet AC specifications such as slew rate and bandwidth. For 3.3 V systems, consider the TLV2464 or OPA4340 families.
What is the typical input bias current of the TLC075IDR at 125°C and 12 V supply?
At 125°C and 12 V supply, the TLC075IDR exhibits typical input bias current of 700 pA (maximum), as specified in the "Electrical Characteristics" table for TLC07XI grade devices across full temperature range. This value is consistent across VDD = 5 V and 12 V conditions and enables high-impedance sensor interfacing without significant DC error.
