Product details
Overview
TLC075AIDR from Texas Instruments is a quad-channel, single-supply operational amplifier featuring 10 MHz gain-bandwidth, ±50 mA high-output-drive capability, 16 V/μs positive slew rate, 4.5–16 V supply range, and integrated shutdown control. It operates across −40°C to 125°C and is used in precision analog front-ends for industrial sensor signal conditioning.
For engineers reviewing the TLC075AIDR datasheet, TLC075AIDR pinout, TLC075AIDR application, or TLC075AIDR equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options - all grounded in TI's SLOS219F datasheet and official packaging documentation.
Technical Context
The TLC075AIDR employs TI's patented LBC3 BiCMOS process, combining a CMOS input stage (ultra-high impedance, 7 nV/√Hz noise) with a bipolar output stage (±50 mA drive), enabling both precision and power delivery in a single-supply architecture. Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) supports wide dynamic signal capture.
It integrates per-amplifier shutdown control (SHDN pins), delivering 125 μA/channel quiescent current in shutdown mode while maintaining fast enable/disable timing (0.47 μs turn-on, 2.5 μs turn-off at VDD = 12 V). Phase margin remains stable (≥37°) up to 50 pF load capacitance without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - enables stable unity-gain buffer or 10× gain amplification up to 1 MHz without phase reversal. |
| Output drive current | ±50 mA - drives low-impedance loads (e.g., 600 Ω audio lines or capacitive DAC buffers) without external boost stages. |
| Slew rate (SR+ / SR−) | 16 V/μs / 19 V/μs - supports clean 10 VPP signals at >1 MHz in fast-settling applications like active filters. |
| Input offset voltage (max) | 2 mV over full temperature range - ensures ≤0.2% gain error in 1 V full-scale instrumentation amplifiers. |
| Supply current per channel | 2.9 mA at VDD = 12 V - balances performance and power in multi-channel systems requiring <12 mA total quiescent draw. |
| Shutdown current per channel | 250 μA max - reduces system standby power by >90% versus active operation, critical for battery-backed modules. |
| Common-mode input range | 0.5 V to VDD−0.8 V - accepts signals within 0.5 V of ground and 0.8 V below rail, simplifying single-supply sensor interfacing. |
Pinout & Package
Package: 16-pin SOIC (D package), 1.27 mm pitch, body size 10.3 × 6.6 mm, RoHS-compliant, tape-and-reel (R suffix).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - directly drives loads up to ±50 mA; requires local 100 nF bypass to GND. |
| 2 | 1IN− | Inverting input for Channel A - high-impedance node; guard ring recommended for low-noise PCB layout. |
| 3 | 1IN+ | Non-inverting input for Channel A - supports rail-to-rail common-mode range; connects to sensor reference or feedback divider. |
| 4 | VDD | Positive supply rail - must be decoupled with ≥1 μF ceramic + 100 nF ceramic close to pin 4. |
| 5 | 2IN+ | Non-inverting input for Channel B - electrically isolated from other channels; shares no internal routing with Channel A. |
| 6 | 2IN− | Inverting input for Channel B - matched to pin 2 for inter-channel crosstalk < −140 dB at 1 kHz. |
| 7 | 2OUT | Amplifier B output - independent output stage; capable of simultaneous sourcing/sinking with Channel A. |
| 8 | 1/2SHDN | Shared shutdown control for Channels A and B - logic-high (>2 V) enables both amps; logic-low (<0.8 V) disables them. |
| 9 | 4OUT | Amplifier D output - fourth independent output; identical drive strength and thermal characteristics as pin 1. |
| 10 | 4IN− | Inverting input for Channel D - part of fully differential quad topology; no internal connection to pins 2 or 6. |
| 11 | 4IN+ | Non-inverting input for Channel D - supports same VICR as pin 3; used in multi-stage programmable gain amplifiers. |
| 12 | GND | Analog ground reference - dedicated low-impedance return path; must connect to system AGND plane under device footprint. |
| 13 | 3IN+ | Non-inverting input for Channel C - enables true 4-channel parallel processing without shared bias networks. |
| 14 | 3IN− | Inverting input for Channel C - matched input pair with pin 13; supports balanced differential input configurations. |
| 15 | 3OUT | Amplifier C output - delivers identical AC/DC performance as other channels; usable for dual-supply virtual ground generation. |
| 16 | 3/4SHDN | Shared shutdown control for Channels C and D - independent of pin 8, allowing asymmetric channel enable/disable sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS input/output architecture | Combines 1000 GΩ CMOS input impedance with ±50 mA bipolar output drive - eliminates need for external FET buffers in high-Z sensor interfaces. |
| Integrated per-pair shutdown | Dual independent SHDN pins (pins 8 and 16) allow selective activation of Channel pairs - reduces dynamic power in time-multiplexed ADC drivers. |
| 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 - enables direct connection to 0–5 V or 0–12 V sensor outputs without level-shifting. |
| Low 7 nV/√Hz input voltage noise | Minimizes noise contribution in gain stages preceding 24-bit delta-sigma ADCs - preserves ENOB in precision measurement systems. |
| Stable phase margin ≥37° | Maintains stability driving 50 pF capacitive loads without external compensation - simplifies design of anti-aliasing filters and DAC output buffers. |
| Wide 4.5–16 V supply range | Supports operation from single Li-ion (4.2 V) to industrial 12 V rails - eliminates need for separate LDOs in mixed-voltage systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IDR | Lower bandwidth (2.8 MHz), lower output drive (±35 mA), higher input offset (2.5 mV max), no shutdown function. | Targeted at low-power, cost-sensitive applications where speed and drive strength are secondary to quiescent current (600 μA/channel). | Choose TLV2474IDR only when bandwidth <3 MHz and no shutdown are acceptable; not suitable for high-fidelity audio or fast-settling DAQ. |
| OPA4197IPW | Higher precision (10 μV max VIO), rail-to-rail I/O, lower noise (5.5 nV/√Hz), but limited output drive (±25 mA) and no shutdown. | Optimized for ultra-precision, low-noise applications such as weigh scales and high-resolution data loggers. | Choose OPA4197IPW when offset and noise dominate requirements; avoid if driving <1 kΩ loads or requiring power gating. |
Compared with TLV2474IDR and OPA4197IPW, the TLC075AIDR uniquely balances high-speed (10 MHz), high-output-drive (±50 mA), and integrated shutdown - making it the only option among the three that supports both precision signal conditioning and dynamic power management in space-constrained industrial modules.

FAQ
What is the operating temperature range for the TLC075AIDR?
The TLC075AIDR is rated for operation from −40°C to +125°C, meeting extended industrial temperature requirements. This range is confirmed in the "Recommended Operating Conditions" table of the SLOS219F datasheet and applies to all electrical specifications unless otherwise noted. The "I" suffix in TLC075AIDR explicitly denotes this extended temperature grade, ensuring reliability in harsh environments such as motor control enclosures or outdoor sensor nodes.
Does the TLC075AIDR support rail-to-rail input operation?
Yes, the TLC075AIDR supports rail-to-rail input common-mode voltage from 0.5 V above GND to VDD−0.8 V, as specified in the "Recommended Operating Conditions" section of the SLOS219F datasheet. This allows direct interfacing with sensors and DACs operating near ground or supply rails without external level-shifting circuitry - a key advantage over older TL07x predecessors.
How many independent shutdown controls does the TLC075AIDR have?
The TLC075AIDR has two independent shutdown controls: pin 8 (1/2SHDN) disables Channels A and B, while pin 16 (3/4SHDN) disables Channels C and D. Each control requires a logic-high voltage ≥2 V to enable and ≤0.8 V to disable, drawing only 125 μA/channel in shutdown mode. This dual-control architecture enables flexible power sequencing in multi-channel systems.
What is the maximum capacitive load the TLC075AIDR can drive stably?
The TLC075AIDR maintains ≥37° phase margin driving up to 50 pF capacitive loads, as verified in Figure 20 of the SLOS219F datasheet at VDD = 12 V. For loads exceeding 50 pF, external isolation resistors (e.g., 10–50 Ω in series with the output) are recommended to preserve stability - a design practice confirmed in TI's application notes for high-drive op-amps.
Is the TLC075AIDR pin-compatible with other devices in the TLC07x family?
No - the TLC075AIDR uses a 16-pin SOIC (D) package with a unique pinout optimized for quad-channel operation and dual shutdown control. It is not pin-compatible with the 14-pin TLC074 or 8-pin TLC070/71 variants. Layout reuse requires verification against the "TLC075 D PACKAGE PIN OUTS" diagram on page 3 of SLOS219F, as pin functions differ significantly across the family.
