Product details
Overview
TLC085CD from Texas Instruments is a quad-channel BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), delivering 10 MHz bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It integrates shutdown control per channel pair and supports rail-to-rail input common-mode range down to ground - enabling use in audio line drivers, sensor signal conditioning, and industrial analog front-ends.
For engineers reviewing the TLC085CD datasheet, TLC085CD pinout, TLC085CD application, or TLC085CD equivalent, key selection criteria include guaranteed shutdown functionality, high-output-drive capability into low-impedance loads, wide supply voltage tolerance, and verified performance across –40°C to 125°C industrial temperature range.
Technical Context
The TLC085CD implements a CMOS-input/bipolar-output BiMOS architecture that combines ultralow input bias current (≤100 pA) with high-current sourcing/sinking (±57 mA). Its dual-pair shutdown logic (pins 8 and 16) independently disables channels 1–2 and 3–4, reducing quiescent current to 125 µA per active channel.
Designed for stability with capacitive loads up to 50 pF, it maintains ≥32° phase margin at unity gain and delivers <0.012% THD+N at 1 kHz with 3 VPP output into 10 kΩ - confirming suitability for precision AC-coupled amplification without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables stable closed-loop gain up to 10× at 1 MHz for anti-aliasing or active filtering. |
| Output Drive | ±57 mA - drives 600 Ω audio loads or 10 kΩ instrumentation lines without external buffers. |
| Slew Rate | +16 V/µs / –19 V/µs - supports fast transient response in pulse amplification and DAC output buffering. |
| Input Offset Voltage | 390 µV (typ) - ensures ≤1 mV total error in 12-bit precision signal chains with gain ≤10. |
| Supply Range | 4.5 V to 16 V - operates directly from 5 V, 12 V, or unregulated wall adapters without LDO pre-regulation. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >93% versus active mode (1.9 mA/channel). |
| Input Noise | 8.5 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor interfaces such as thermopile or bridge amplifiers. |
Pinout & Package
Package: 16-pin SOIC (D package), 1.27 mm pitch, body size 10.3 mm × 6.6 mm, RoHS-compliant, rated for 0°C to 70°C (C-suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | High-drive output capable of ±57 mA into resistive or capacitive loads. |
| 2 | Channel 1 Inverting Input | Differential input node with 1000 GΩ input resistance and 22.9 pF capacitance. |
| 3 | Channel 1 Non-Inverting Input | Common-mode range extends to GND - enables single-supply transducer interfacing. |
| 4 | Positive Supply (VDD) | Accepts 4.5 V–16 V; internal regulation ensures consistent bias under supply ripple. |
| 5 | Channel 2 Non-Inverting Input | Independent input for second op-amp stage; matched offset and noise vs. Channel 1. |
| 6 | Channel 2 Inverting Input | Configurable as summing node or feedback path; supports unity-gain stable configurations. |
| 7 | Channel 2 Output | Electrically isolated from Channel 1 output; no crosstalk above –60 dB @ 100 kHz. |
| 8 | Channel 1–2 Shutdown | Logic-low (≤0.8 V) disables both Channel 1 and 2; draws ≤250 µA in shutdown. |
| 9 | Channel 3 Output | Identical drive and AC specs to Channel 1; shares thermal substrate with Channel 4. |
| 10 | Channel 3 Inverting Input | Matched input characteristics enable multi-stage filter topologies with predictable DC error. |
| 11 | Channel 3 Non-Inverting Input | Supports rail-to-rail input operation; VICR = GND to VDD–2 V at full temperature range. |
| 12 | Ground (GND) | Single reference for all four amplifiers; layout requires low-impedance star connection. |
| 13 | Channel 4 Non-Inverting Input | Enables independent biasing of fourth channel; no internal connection to other non-inverting inputs. |
| 14 | Channel 4 Inverting Input | Compatible with standard op-amp feedback networks; supports gain-setting resistors ≥1 kΩ. |
| 15 | Channel 4 Output | Delivers same slew rate and settling time as Channels 1–3; validated for 50 pF load stability. |
| 16 | Channel 3–4 Shutdown | Independent control of last two channels; allows partial system power gating. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS front-end (low IIB, high Zin) with bipolar output stage (high IO, low Zout) for optimal AC/DC trade-off. |
| Per-Pair Shutdown Control | Two independent SHDN pins (8 and 16) allow selective disabling of Channel 1–2 or 3–4 to manage dynamic power. |
| Rail-to-Rail Input Common-Mode Range | VICR includes GND, enabling direct interface with 0–5 V sensors and ADC references without level-shifting. |
| Stable with Capacitive Loads | Guaranteed phase margin ≥32° with 50 pF load - eliminates need for isolation resistors in driving cables or ADC inputs. |
| Low 1/f Noise Corner | Input voltage noise flat at 8.5 nV/√Hz from 1 kHz - critical for precision DC-coupled measurement systems. |
| Industrial Temperature Rating | Specified over –40°C to 125°C (I-suffix), but TLC085CD is C-suffix (0°C to 70°C) - suitable for commercial-grade embedded 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 |
|---|---|---|---|
| TL084CD | Lower bandwidth (3 MHz), no shutdown, higher input offset (3 mV max), BiFET process. | Lacks per-pair shutdown and rail-to-rail input; unsuitable for low-voltage sensor interfaces. | Select TL084CD only if cost is primary constraint and system operates at <1 MHz with dual supplies. |
| OPA4134UA | FET-input, lower noise (4.8 nV/√Hz), no shutdown, ±15 V max supply, higher price. | Superior audio performance but incompatible with 5 V-only systems and lacks power-gating capability. | Choose OPA4134UA for high-fidelity audio where power efficiency and shutdown are not required. |
Compared with TL084CD and OPA4134UA, the TLC085CD uniquely balances wide bandwidth, integrated shutdown, single-supply operation, and industrial-grade output drive - making it the only option supporting dynamic power management in space-constrained 5 V embedded systems.

FAQ
What is the operating temperature range for the TLC085CD?
The TLC085CD is specified for commercial temperature operation from 0°C to 70°C. This differs from the I-suffix variants (e.g., TLC085ID), which extend to –40°C to 125°C. The C-suffix version is intended for indoor, non-extreme environments such as consumer audio gear or office automation equipment where ambient temperatures remain within this band. Thermal derating is not required below 70°C.
Does the TLC085CD support rail-to-rail input operation?
Yes, the TLC085CD supports rail-to-rail input common-mode voltage range down to GND (VICR = GND to VDD–2 V). This allows direct interfacing with 0 V–referenced sensors and ADC references without level-shifting circuitry. However, output swing is not rail-to-rail - VOH reaches VDD–1.5 V and VOL sinks to 0.5 V under full load, as confirmed in the Electrical Characteristics table.
How does the shutdown function work on the TLC085CD?
The TLC085CD features two independent shutdown pins: Pin 8 controls Channels 1 and 2, while Pin 16 controls Channels 3 and 4. Applying ≤0.8 V to either pin disables the corresponding pair, reducing supply current to 125 µA per channel. Both pins must be pulled high (>2 V) to enable all four channels. No external pull-up resistors are required - internal biasing ensures defined state during power-up.
Can the TLC085CD drive a 600 Ω load at 12 V supply?
Yes, the TLC085CD can drive a 600 Ω load at 12 V supply, delivering ±57 mA output current with VOH = 10.3 V and VOL = 0.65 V at 25°C. This meets professional audio line-driving requirements (e.g., AES3 interface levels) and remains stable with up to 50 pF capacitive loading - verified in the Phase Margin vs Load Capacitance plots (Figures 19–20).
What is the typical input offset voltage for the TLC085CD?
The typical input offset voltage for the TLC085CD is 390 µV at 25°C and VDD = 5 V, with a maximum of 3000 µV across the full 0°C to 70°C range. At VDD = 12 V, typical VIO remains 390 µV, and max stays at 3000 µV. This specification is confirmed in the Electrical Characteristics tables on pages 4 and 6 of the SLOS254F datasheet.
