Product details
Overview
TLC083CDR from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V, featuring shutdown control, 8.5 nV/√Hz input noise, and rail-to-rail input common-mode range down to ground - used in audio line drivers, sensor signal conditioning, and industrial analog front-ends.
For engineers reviewing the TLC083CDR datasheet, TLC083CDR pinout, TLC083CDR application, or TLC083CDR equivalent, this page delivers verified electrical specifications, package mapping to SOIC-14, functional pin definitions, real-world use cases, and two validated alternative parts with documented differences in channel count, shutdown capability, and thermal performance.
Technical Context
The TLC083CDR implements a CMOS-input/bipolar-output BiMOS architecture enabling both ultralow input bias current (≤100 pA) and high output drive (57 mA sourcing / 55 mA sinking), with independent shutdown control per amplifier pair. Its gain-bandwidth product remains stable at 10 MHz across supply voltages from 4.5 V to 16 V.
It supports true single-supply operation with VICR extending to GND and VDD–2 V, features matched slew rates (SR+ = 16 V/µs, SR– = 19 V/µs), and maintains phase margin ≥32° into 50 pF loads - critical for driving capacitive cables or ADC input networks without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and low-speed data acquisition frequencies. |
| Output Drive | ±55 mA - drives 600 Ω loads directly, eliminating external buffer stages in line-driver applications. |
| Slew Rate | 16 V/µs (positive), 19 V/µs (negative) - supports fast transient response in pulse-amplification and active filter designs. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in precision sensor interfaces and low-level signal chains. |
| Supply Range | 4.5 V to 16 V - operates from single Li-ion battery (4.2 V nominal) up to industrial 12 V rails without level-shifting. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >93% versus active mode (1.9 mA/channel). |
| Input Offset | 60 µV (typical) - minimizes DC error in closed-loop gain stages and precision instrumentation amplifiers. |
Pinout & Package
Package: SOIC-14 (D package), 14-pin plastic small-outline integrated circuit, surface-mount, tape-and-reel (R suffix). Pin 1 marked by beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load; capable of ±55 mA continuous current. |
| 2 | 1IN− | Inverting input of Amp A - high-impedance CMOS node (≥1 TΩ), low bias current (≤100 pA). |
| 3 | 1IN+ | Non-inverting input of Amp A - supports common-mode voltage from GND to VDD–2 V. |
| 4 | GND | Analog ground reference - must be low-impedance connection to minimize noise coupling between channels. |
| 5 | 2IN+ | Non-inverting input of Amp B - electrically isolated from Amp A inputs; same VICR spec. |
| 6 | 2IN− | Inverting input of Amp B - matched offset and bias characteristics to Pin 2. |
| 7 | 2OUT | Amplifier B output - independently driven; shares no internal nodes with Pin 1. |
| 8 | 1/2SHDN | Shared shutdown control - logic-low (≤0.8 V) disables both amplifiers; logic-high (≥2 V) enables both. |
| 9 | 4OUT | Not connected on TLC083 - NC; no internal bond wire or circuitry. |
| 10 | 4IN− | Not connected on TLC083 - NC; unused pin per device family pinout definition. |
| 11 | 4IN+ | Not connected on TLC083 - NC; reserved for higher-channel variants (e.g., TLC084/085). |
| 12 | VDD | Positive supply - accepts 4.5 V to 16 V; decoupling capacitor required at pin. |
| 13 | 3IN+ | Not connected on TLC083 - NC; no internal connection. |
| 14 | 3/4SHDN | Not connected on TLC083 - NC; shutdown function only implemented on Pin 8. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to GND and within 2 V of VDD - eliminates level-shifting in single-supply sensor interfaces. |
| Independent dual-channel shutdown | Single SHDN pin (Pin 8) controls both amplifiers simultaneously - simplifies power sequencing in multi-stage analog systems. |
| High-output-current bipolar stage | Delivers ±55 mA while maintaining 10 MHz GBW - enables direct drive of low-Z loads like relays, LEDs, or coaxial cables. |
| Low-noise CMOS input stage | 8.5 nV/√Hz input voltage noise + ≤100 pA input bias current - ideal for high-gain transducer amplification without added Johnson noise. |
| Stable into capacitive loads | Maintains ≥32° phase margin with 50 pF load - ensures stability when driving ADC sample capacitors or long PCB traces. |
Applications
| Audio Line Driver | Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC082CDR | No shutdown functionality; identical SOIC-8 package; same 10 MHz GBW and ±55 mA drive. | Cannot support power-gated signal paths; requires external enable circuitry for low-power modes. | Select when shutdown is unnecessary and board space is constrained (SOIC-8 vs SOIC-14). |
| OPA2350UA | Rail-to-rail I/O; lower noise (7 nV/√Hz); lower supply current (1.8 mA/ch); no shutdown; SOIC-8. | Lacks high-current drive (max ±40 mA); unsuitable for 600 Ω loads or relay drivers. | Select for ultra-low-noise, low-power, rail-to-rail output apps where drive strength is secondary. |
Compared with TLC083CDR, TLC082CDR saves PCB area but forfeits power management, while OPA2350UA improves noise and quiescent current but sacrifices output drive - making TLC083CDR uniquely suited for high-fidelity, high-drive, single-supply analog systems requiring dynamic power control.

FAQ
What is the operating temperature range for the TLC083CDR?
The TLC083CDR is rated for commercial temperature operation from 0°C to 70°C. This is indicated by the "C" suffix in the part number. It is not rated for the extended –40°C to 125°C range (which would require the "I" suffix, e.g., TLC083IDR). The datasheet specifies all electrical characteristics under these ambient conditions unless otherwise noted.
Does the TLC083CDR support true rail-to-rail output swing?
No, the TLC083CDR does not provide rail-to-rail output. Its output voltage swing is typically within 1.5 V of each rail under 5 mA load (e.g., VOH ≈ VDD – 1.5 V, VOL ≈ 1.5 V). However, it does feature rail-to-rail *input* common-mode range (VICR from GND to VDD – 2 V), which is explicitly confirmed in the datasheet's Recommended Operating Conditions table.
How is shutdown controlled on the TLC083CDR?
Shutdown is controlled via Pin 8 (1/2SHDN). Driving this pin to ≤0.8 V (logic low) places both amplifiers into ultralow-power mode (IDD(SHDN) = 125 µA/channel). Driving it to ≥2 V (logic high) enables normal operation. The pin has no internal pull-up or pull-down; external logic or microcontroller GPIO must assert the level.
Can the TLC083CDR drive a 600 Ω load at 10 VPP without distortion?
Yes. At VDD = 12 V, the TLC083CDR delivers >10 VPP into 600 Ω with THD+N < 0.005% at 1 kHz (per datasheet Figure 29). Its ±55 mA output current capability and 19 V/µs negative slew rate ensure clean large-signal response, making it suitable for professional audio line-driving applications.
What is the purpose of Pins 9–14 on the TLC083CDR SOIC-14 package?
Pins 9–14 are No-Connect (NC) terminals specific to the TLC083CDR. They are physically present due to shared package footprint with higher-channel variants (TLC084/TLC085), but have no internal bond wires or circuit connections. Per TI's family pinout diagram, they must remain unconnected and may be left floating or tied to GND for mechanical stability - no electrical function is assigned.
