Product details
Overview
TLC085IDR from Texas Instruments is a quad-channel BiMOS operational amplifier optimized for single-supply, high-output-drive applications. It delivers 10 MHz bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and operates from 4.5 V to 16 V across –40°C to 125°C - enabling use in automotive sensor signal conditioning and industrial analog front-ends.
For engineers reviewing the TLC085IDR datasheet, TLC085IDR pinout, TLC085IDR application, or TLC085IDR equivalent, key selection criteria include guaranteed rail-to-rail input (VICR = GND to VDD–2 V), ultralow shutdown current (125 µA/channel), and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The TLC085IDR integrates a low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high impedance (>1 GΩ differential input resistance), low input noise (8.5 nV/√Hz), and robust output drive (55 mA sink / 57 mA source) under single-supply conditions.
Its dedicated shutdown control (SHDN) pin enables independent channel disable with fast turnoff time (2.5 µs at VDD = 12 V), while internal offset nulling capability supports precision DC-coupled configurations without external trim components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - supports stable closed-loop gain up to 10× at audio and ultrasonic frequencies. |
| Output Drive | ±57 mA - drives 600 Ω loads directly without external buffers in line-driver or actuator interface roles. |
| Slew Rate | +16 V/µs / –19 V/µs - preserves fidelity of fast transient signals such as pulse-width modulated motor control feedback. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and wide-input industrial rails without regulation overhead. |
| Input Offset | 60 µV - enables sub-mV accuracy in precision instrumentation amplifiers and sensor offset correction circuits. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >93% versus active operation (1.9 mA/channel). |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive and factory-floor industrial environments. |
Pinout & Package
TLC085IDR is packaged in a 16-pin TSSOP (PWP) with exposed thermal pad, offering compact footprint (5 mm × 4.4 mm) and enhanced thermal performance (θJA = 26.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | OUTx | Amplifier output terminals for channels 1–4; each capable of sourcing/sinking ±57 mA into resistive or capacitive loads. |
| 2, 6, 10, 14 | INx– | Inverting inputs; support unity-gain stable configurations and precise differential signal amplification. |
| 3, 7, 11, 15 | INx+ | Non-inverting inputs; feature rail-to-rail common-mode range (GND to VDD–2 V) for single-supply sensor interfacing. |
| 4 | VDD | Positive supply rail; accepts 4.5 V–16 V with internal overvoltage protection up to 17 V absolute max. |
| 8 | GND | Analog ground reference; requires low-impedance connection to minimize noise coupling between channels. |
| 12 | 1/2SHDN | Shared shutdown control for channels 1 & 2; logic-low (<0.8 V) disables both outputs and reduces IDD to 125 µA total. |
| 16 | 3/4SHDN | Shared shutdown control for channels 3 & 4; independent of 1/2SHDN for flexible power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends usable input voltage from GND to VDD–2 V - eliminates level-shifting circuitry in single-supply data acquisition systems. |
| Dual independent shutdown controls | 1/2SHDN and 3/4SHDN pins allow selective channel disabling - critical for dynamic power management in multi-sensor modules. |
| Low input noise density | 8.5 nV/√Hz at 1 kHz - preserves SNR in low-level transducer amplification (e.g., piezoelectric sensors, strain gauges). |
| High open-loop gain | 120 dB (min) at VDD = 12 V - ensures <0.01% gain error in 100× closed-loop configurations with 10 kΩ feedback networks. |
| Phase margin stability | 37° at CL = 50 pF (VDD = 12 V) - maintains stability driving long cables or capacitive DAC reference buffers without external compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9054IPWR | Lower supply current (0.53 mA/ch), lower bandwidth (5 MHz), no shutdown pins, SC70-16 package. | Lacks independent shutdown controls; unsuitable for dynamic channel power gating. | Select when ultra-low quiescent current dominates over output drive and shutdown flexibility. |
| OPA4991IPW | Higher precision (12 µV max VIO), lower noise (4.2 nV/√Hz), no shutdown, wider supply (2.7–36 V), TSSOP-14. | 14-pin TSSOP lacks dedicated SHDN pins; requires external logic for power control. | Select when sub-µV offset and ultra-low noise are mandatory, and shutdown is implemented externally. |
Compared with TLV9054IPWR and OPA4991IPW, TLC085IDR uniquely combines quad-channel shutdown control, ±57 mA output drive, and rail-to-rail input in a 16-pin TSSOP - making it optimal for space-constrained, power-aware industrial and automotive analog subsystems where per-channel power management is required.

FAQ
What is the maximum supply voltage rating for TLC085IDR?
The absolute maximum supply voltage for TLC085IDR is 17 V, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent device damage. The recommended operating range is 4.5 V to 16 V, ensuring full specification compliance across the –40°C to 125°C temperature range. This makes TLC085IDR suitable for 12 V automotive and industrial systems with transient overvoltage margins.
Does TLC085IDR support true rail-to-rail input operation?
TLC085IDR supports rail-to-rail input common-mode voltage from GND to VDD–2 V, verified across its full operating temperature range. While not extending fully to the positive rail, this range accommodates most single-supply sensor interfaces (e.g., bridge sensors, thermocouples) without level-shifting circuitry. Input offset voltage remains stable within this range, with typical VIO = 60 µV at 25°C and max 3000 µV over full temperature.
How does the shutdown function operate on TLC085IDR?
TLC085IDR features two independent shutdown controls: pin 12 (1/2SHDN) disables channels 1 and 2, while pin 16 (3/4SHDN) disables channels 3 and 4. A logic-low voltage ≤0.8 V on either pin reduces the corresponding channel's supply current to 125 µA (typ), with turnoff time of 2.5 µs at VDD = 12 V. Both controls are CMOS-compatible and require no pull-up resistors.
What is the output current capability of TLC085IDR under load?
TLC085IDR delivers ±57 mA output current per channel - sourcing 57 mA at VDD–1.5 V and sinking 55 mA at 0.5 V - verified at 25°C and maintained across –40°C to 125°C. This enables direct drive of 600 Ω loads (e.g., line drivers, solenoid interfaces) without external buffers. Short-circuit output current exceeds ±150 mA, providing robust fault tolerance.
Is TLC085IDR pin-compatible with other devices in the TLC08x family?
TLC085IDR uses a 16-pin TSSOP (PWP) package with unique pinout optimized for quad-channel operation and dual shutdown control. It is not pin-compatible with TLC084IDR (14-pin TSSOP, no shutdown) or TLC082IDR (8-pin SOIC). Pin mapping must be verified against the official TLC085-specific diagram - particularly the placement of 1/2SHDN (pin 12) and 3/4SHDN (pin 16), which differ from other family members.
