Product details
Overview
TLC070CDR from Texas Instruments is a single-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. It features ultralow input offset voltage (60 µV typ), low input noise (7 nV/√Hz), and integrated shutdown control - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC070CDR datasheet, TLC070CDR pinout, TLC070CDR application, or TLC070CDR equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical context - including its SOIC-8 footprint, 16 V/µs slew rate, shutdown timing (0.15 µs turn-on), and compatibility with rail-to-rail output loads up to ±50 mA.
Technical Context
The TLC070CDR implements a CMOS-input/bipolar-output BiMOS architecture that combines high input impedance (>1 TΩ differential resistance) with robust output drive capability. Its internal shutdown logic responds to TTL-compatible SHDN pin thresholds (VIH ≥ 2 V, VOL ≤ 0.8 V), enabling fast enable/disable transitions (ton = 0.15 µs, toff = 1.3 µs) while reducing quiescent current from 1.9 mA to 125 µA per channel.
Designed for stability with capacitive loads up to 100 pF, it maintains phase margin ≥32° (CL = 50 pF) and gain margin ≥2.2 dB across 4.5–16 V supply range. The device operates over 0°C to 70°C (C-suffix) and supports common-mode input ranges from 0.5 V to (VDD − 0.8 V), making it suitable for DC-coupled single-supply systems without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable unity-gain buffer or 10× inverting amplifier up to 1 MHz. |
| Slew Rate | +16 V/µs / −19 V/µs - supports clean 1-V step response within 0.18 µs (0.1% settling, CL = 10 pF). |
| Output Drive | ±55 mA continuous - drives 600 Ω loads at full swing with <0.012% THD+N at 1 kHz (AV = 10). |
| Input Offset Voltage | 60 µV typical (25°C) - reduces DC error in precision transimpedance or instrumentation amplifier stages. |
| Supply Range | 4.5 V to 16 V single supply - eliminates dual-rail complexity in battery-powered or industrial 12-V systems. |
| Shutdown Current | 125 µA per channel - cuts total system power by >93% during idle periods in portable or energy-conscious designs. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge). |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel (R suffix), 3.9 mm × 4.9 mm body, 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pad; no routing or grounding required. |
| 2 | IN− | Inverting input - high-impedance CMOS node (1 TΩ); accepts DC-coupled signals within VICR (0.5 V to VDD−0.8 V). |
| 3 | IN+ | Non-inverting input - matched to IN− for low offset; used in follower, summing, or differential configurations. |
| 4 | GND | Analog ground reference - must be low-impedance plane; separates from digital ground if mixed-signal layout. |
| 5 | SHDN | Active-high shutdown control - drives to ≥2 V to enable, ≤0.8 V to disable; TTL/CMOS compatible. |
| 6 | VDD | Positive supply rail - accepts 4.5–16 V; decoupling capacitor (0.1 µF ceramic) required at pin. |
| 7 | OUT | Amplified output - delivers ±55 mA into resistive loads; stable with up to 100 pF capacitive load. |
| 8 | NULL | No internal connection - unused pad; no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS front-end (low IB, low VIO) with bipolar output stage (high IO, low Zo) - achieves 7 nV/√Hz noise + ±55 mA drive in one die. |
| Wide Supply Range | Operates from 4.5 V to 16 V single supply - supports direct integration into 5 V microcontroller systems or 12 V industrial rails without regulators. |
| Integrated Shutdown | Reduces IDD from 1.9 mA to 125 µA with <1.3 µs disable time - enables dynamic power gating in battery-operated data loggers. |
| Rail-to-Rail Output Swing | Drives within 0.5 V of GND and 1.5 V of VDD at full load - maximizes dynamic range in single-supply ADC driver applications. |
| High PSRR & CMRR | 100 dB PSRR and 95 dB CMRR (typ) - rejects supply ripple and common-mode interference in noisy industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Lower bandwidth (3 MHz), higher VIO (1.5 mV max), no shutdown, 1.4 mA IDD - BiFET process, no MSOP option. | Lacks shutdown and output drive; unsuitable for power-sensitive or high-current line driving. | Select TL071CP only when cost is primary constraint and 10 MHz bandwidth or 55 mA drive is unnecessary. |
| OPA2340UA | Rail-to-rail input/output, lower noise (5.5 nV/√Hz), but lower output drive (30 mA), no shutdown, 1.8 mA IDD. | Better for ultra-low-voltage (2.7–5 V) or RRO-critical apps; cannot replace TLC070CDR where >40 mA load or shutdown is required. | Choose OPA2340UA for battery-powered sensor nodes needing RRO and sub-5 V operation - not for 12 V industrial drivers. |
Compared with TL071CP and OPA2340UA, the TLC070CDR uniquely balances 10 MHz bandwidth, ±55 mA output, shutdown control, and 4.5–16 V operation - making it the only option among the three for high-fidelity, single-supply, high-current analog output stages requiring dynamic power management.

FAQ
What is the operating temperature range for the TLC070CDR?
The TLC070CDR is rated for commercial temperature operation from 0°C to 70°C, as indicated by the "C" suffix in the part number. This range is validated per TI's SLOS219F datasheet and applies to all electrical characteristics unless otherwise noted. It is not rated for extended industrial (−40°C to 125°C) operation - that requires the "I" or "AI" variants such as TLC070IDR.
Does the TLC070CDR support rail-to-rail input or output?
The TLC070CDR supports rail-to-rail output swing - delivering within 0.5 V of GND and 1.5 V of VDD under full load - but does not feature rail-to-rail input. Its common-mode input voltage range is specified from 0.5 V to (VDD − 0.8 V), meaning it cannot accept signals at the negative rail (GND) or within 0.8 V of VDD without degradation.
How does the shutdown function work on the TLC070CDR?
The TLC070CDR's SHDN pin (Pin 5) is active-high: applying ≥2 V enables normal operation (IDD ≈ 1.9 mA), while ≤0.8 V places the amplifier in shutdown (IDD ≈ 125 µA). Turn-on time is 0.15 µs and turn-off time is 1.3 µs - defined as the interval until supply current reaches 50% of final value. No external pull-up is required.
Can the TLC070CDR drive a 600 Ω load at 10 Vpp with low distortion?
Yes - the TLC070CDR delivers 0.005% THD+N at 1 kHz into 600 Ω with 8 Vpp output (VDD = 12 V), per SLOS219F Figure 28. At 10 Vpp, it remains linear with <0.01% distortion under same conditions, leveraging its ±55 mA output drive and 16 V/µs slew rate to avoid slewing-induced harmonic generation.
What is the package type and lead count for the TLC070CDR?
The TLC070CDR uses an 8-pin SOIC (Small Outline Integrated Circuit) package, designated "D" in TI's packaging nomenclature. It measures 3.9 mm × 4.9 mm with 1.27 mm lead pitch and is supplied in tape-and-reel format (indicated by the "R" suffix). Pins 1 and 8 are NC (no internal connection) and must remain unconnected.
