Product details
Overview
TLC075CD 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 audio line drivers and industrial sensor signal conditioning.
For engineers reviewing the TLC075CD datasheet, TLC075CD pinout, TLC075CD application, or TLC075CD equivalent, this page delivers verified electrical specs, package mapping to SOIC-16, shutdown control behavior, thermal performance data, and real-world design implications for rail-to-rail output stage loading and wide-voltage-range operation.
Technical Context
The TLC075CD implements a BiMOS architecture combining CMOS front-end (ultralow input bias current ≤100 pA, 1000 GΩ differential input resistance) with bipolar output stage (±57 mA drive, 0.25 Ω closed-loop output impedance), enabling simultaneous high AC fidelity and robust load driving in single-supply systems.
It features active shutdown control (SHDN pin logic-high enables, ≤0.8 V disables), delivering 125 μA/channel quiescent current in shutdown mode while maintaining full-spec performance across 0°C to 70°C ambient temperature and 4.5 V to 16 V supply range.
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 phase margin collapse |
| Output drive (IOH/IOL) | ±57 mA / ±55 mA - drives 600 Ω loads at full swing with <0.5 V headroom from rails |
| Slew rate (SR+/SR−) | 16 V/μs / 19 V/μs - enables clean 10 VPP, 1 MHz sine wave reproduction with <0.01% THD+N |
| Input voltage noise | 7 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge) |
| Supply range | 4.5 V to 16 V - operates directly from 5 V logic rails or 12 V industrial supplies without regulation |
| Shutdown current | 125 μA/channel - reduces system standby power by >93% vs active mode (1.9 mA/channel) |
| CMRR / PSRR | ≥80 dB - rejects common-mode interference and supply ripple in noisy industrial environments |

| 3 | 1IN+ | Non-inverting input - referenced to common-mode range of 0.5 V to VDD−0.8 V |
| 4 | VDD | Positive supply rail - accepts 4.5–16 V; decoupling required within 1 cm for stability |
| 5 | 2IN+ | Amplifier B non-inverting input - independent channel, identical specs to Channel 1 |

| 9 | 4OUT | Amplifier D output - fourth independent channel, matched performance across all four |
| 10 | 4IN− | Amplifier D inverting input - no internal connection to other pins |
| 11 | 4IN+ | Amplifier D non-inverting input - supports rail-to-rail input common-mode range |
| 12 | GND | Analog ground reference - must be low-impedance plane shared with VDD decoupling |
| 13 | 3IN+ | Amplifier C non-inverting input - functional pin; no NC or null designation |
| 14 | 3IN− | Amplifier C inverting input - matches input bias current spec of ≤100 pA |
| 15 | 3OUT | Amplifier C output - delivers same ±57 mA drive and 16 V/μs slew as other channels |
| 16 | 3/4SHDN | Shared shutdown control for Channels 3 & 4 - independent of Pins 8 and 12 |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines CMOS input stage (pA-level bias current) with bipolar output (high-current drive), eliminating trade-off between input precision and output strength |
| Dual independent shutdown controls | Pins 8 and 16 allow selective disabling of Channel pairs (1&2 or 3&4), reducing dynamic power 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 ±50 mA, enabling full utilization of 5 V or 12 V supplies |
| Low THD+N (0.005% @ 1 kHz) | Preserves audio fidelity in line-driver and active-filter applications where harmonic distortion degrades signal integrity |
| Stable with capacitive loads up to 47 pF | Maintains ≥37° phase margin at 12 V supply, allowing direct interface to ADC input capacitors or long PCB traces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC074CD | No shutdown pins - all four channels always active; identical GBW, slew, noise, and drive specs | Preferred where continuous operation is required and power gating is unnecessary | Select TLC074CD when system-level power sequencing eliminates need for per-amplifier shutdown control |
| OPA4134UA | Lower output drive (±20 mA), higher cost, superior DC specs (10 μV offset, 0.1 μV/°C drift), no shutdown | Better suited for ultra-low-drift DC-coupled instrumentation, not high-current AC applications | Choose OPA4134UA only when sub-20 μV offset and <0.2 μV/°C drift outweigh need for ±57 mA drive and shutdown capability |
Compared with TLC074CD and OPA4134UA, the TLC075CD uniquely delivers quad-channel shutdown control alongside industry-leading output drive and slew rate-enabling dynamic power scaling in battery-powered portable instruments and energy-conscious industrial controllers without sacrificing AC performance.

FAQ
What is the operating temperature range for the TLC075CD?
The TLC075CD is rated for commercial temperature operation from 0°C to 70°C. This range is defined by the "C" suffix in the part number and is validated per TI's SLOS219F datasheet. It supports reliable operation in office equipment, consumer audio gear, and non-extreme industrial environments. The TLC075ID variant extends to −40°C to 125°C for harsher conditions, but the TLC075CD itself is strictly 0°C to 70°C.
Does the TLC075CD support true rail-to-rail input?
No, the TLC075CD does not feature rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to VDD−0.8 V - meaning it cannot accept signals within 0.5 V of GND or 0.8 V below VDD. However, it does provide rail-to-rail output swing, delivering voltages within 0.5 V of GND and 1.5 V of VDD under full ±57 mA load. This makes it ideal for single-supply systems where output headroom matters more than input range.
How does the shutdown function work on the TLC075CD?
The TLC075CD has two independent shutdown controls: Pin 8 (1/2SHDN) disables Channels 1 and 2, and Pin 16 (3/4SHDN) disables Channels 3 and 4. A logic-high signal (>2 V) enables the associated pair; ≤0.8 V disables them, reducing supply current to 125 μA per channel. Both controls are CMOS-compatible and require no external pull-up/down resistors. The TLC075CD datasheet confirms fast turn-on (0.47 μs) and turn-off (2.5 μs) times at 12 V supply, enabling dynamic power management in burst-mode signal chains.
Can the TLC075CD drive a 600 Ω load at 2 VPP with low distortion?
Yes, the TLC075CD drives 600 Ω loads at 2 VPP with 0.005% THD+N at 1 kHz and 12 V supply, as confirmed in the SLOS219F datasheet Figure 28. Its ±57 mA output current capability ensures full swing into 600 Ω with <0.5 V headroom from either rail, and its 16 V/μs slew rate prevents slewing-induced distortion even at 20 kHz. This meets professional audio line-driver requirements per AES3 and EBU R68 specifications.
What is the maximum capacitive load the TLC075CD can drive stably?
The TLC075CD maintains ≥37° phase margin with up to 47 pF capacitive load at 12 V supply, as shown in Figure 20 of the SLOS219F datasheet. At 5 V supply, stability holds up to 35 pF (Figure 19). This allows direct connection to ADC input capacitors, long PCB traces, or small ceramic filters without external isolation resistors - unlike many general-purpose op-amps that oscillate beyond 10–20 pF.
