Product details
Overview
TLC070IDGNR 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 space-constrained industrial sensor interfaces and audio line drivers.
For engineers reviewing the TLC070IDGNR datasheet, TLC070IDGNR pinout, TLC070IDGNR application, or TLC070IDGNR equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in TI's SLOS219F datasheet and official packaging documentation.
Technical Context
The TLC070IDGNR implements a CMOS-input/bipolar-output BiMOS architecture, combining high input impedance (>1 GΩ) with robust output drive capability. Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and fast slew rates (16 V/µs positive, 19 V/µs negative) support dynamic signal acquisition in single-supply data acquisition systems.
It integrates an active shutdown function (SHDN pin) that reduces supply current to 125 µA/channel while maintaining fast enable/disable timing (ton = 0.47 µs, toff = 2.5 µs at VDD = 12 V). The device is rated for −40°C to +125°C operation and supports stable closed-loop performance up to 47 pF capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable unity-gain buffering of signals up to ~1 MHz with minimal phase error. |
| Output Drive | ±55 mA continuous output current - drives heavy loads (e.g., 600 Ω audio lines or PLC analog outputs) without external buffers. |
| Slew Rate | +16 V/µs / −19 V/µs - supports fast settling of 1-V step inputs in <0.2 µs (0.1% error, CL = 47 pF). |
| Input Offset Voltage | 60 µV typical (25°C), ≤2 mV max over full temperature range - ensures <0.01% gain error in precision DC-coupled amplifiers. |
| Supply Range | 4.5 V to 16 V single supply - operates directly from standard industrial rails (5 V, 12 V) without dual-supply complexity. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >93% vs active mode (1.9 mA), critical for battery-backed instrumentation. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor front-ends (e.g., thermocouple or strain gauge amplification). |
Pinout & Package
Package: 8-pin MSOP PowerPAD™ (DGN) with exposed thermal pad - provides 2.37 W power dissipation capability and enhanced thermal performance in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - left unconnected; not used for signal or biasing. |
| 2 | IN− | Inverting input - accepts feedback network or differential signal reference; high-impedance CMOS node. |
| 3 | IN+ | Non-inverting input - connects to sensor output or reference voltage; common-mode range extends to 0.5 V above GND. |
| 4 | GND | Analog ground reference - must be low-impedance; ties to PCB thermal pad for thermal and noise control. |
| 5 | SHDN | Active-high shutdown control - logic high (>2 V) enables amplifier; logic low (<0.8 V) disables output and cuts supply current. |
| 6 | VDD | Positive supply rail - accepts 4.5–16 V; decoupling capacitor required within 5 mm of pin for stability. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±55 mA into resistive or moderate capacitive loads. |
| 8 | NULL | No internal connection - electrically isolated; may be left floating or tied to GND for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (ultra-low IB, high Zin) with bipolar output stage (high IO, low Zout), eliminating trade-offs between precision and drive. |
| MSOP PowerPAD™ Package | 8-pin thermally enhanced MSOP with exposed die pad - reduces θJA to 52.7°C/W, enabling 2.37 W dissipation in compact PCB footprints. |
| Wide Common-Mode Input Range | 0.5 V to VDD−0.8 V - allows direct interfacing with 0–5 V or 0–12 V sensor outputs without level-shifting circuitry. |
| Fast Shutdown Enable/Disable | ton = 0.47 µs, toff = 2.5 µs (VDD = 12 V) - supports rapid power cycling in time-multiplexed sensor systems or energy-aware DAQ. |
| High PSRR & CMRR | 100 dB PSRR and 95 dB CMRR (typ, 25°C) - rejects supply ripple and common-mode interference in noisy industrial environments. |
Applications

IC Role / Device Role: Unity-gain buffer with low THD+N (0.005% at 1 kHz, 8 VPP) and fast slew rate. Use Value: 16 V/µs slew rate prevents slew-induced distortion on transients; shutdown mode cuts idle power in portable devices. |
| Programmable Analog Output Module | Single-Supply Data Acquisition Front-End |
|
Use Scenario: Generating calibrated 0–10 V or 4–20 mA analog outputs in industrial I/O modules using DAC + op-amp current/voltage conversion. IC Role / Device Role: Voltage-to-current converter or precision voltage follower with high open-loop gain (120 dB) and load regulation. Use Value: 10 MHz bandwidth ensures accurate reproduction of DAC update steps; ±55 mA output sustains 4–20 mA loop compliance across 500 Ω loads. |
Use Scenario: Buffering and filtering sensor inputs prior to ADC sampling in condition-monitoring equipment (e.g., vibration, pressure). IC Role / Device Role: Anti-aliasing filter driver and gain stage with low noise, low distortion, and stable phase margin (≥37°). Use Value: 0.1% settling in 0.17 µs (CL = 47 pF) supports high-speed sampling; shutdown mode enables per-channel power gating in multi-channel systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2771IDBVR | Lower bandwidth (2 MHz), lower output drive (±25 mA), but rail-to-rail output and lower quiescent current (1.3 mA). | Better suited for ultra-low-power, low-frequency sensor interfaces where drive strength is secondary. | Select when power budget is tighter than speed or drive requirements - not drop-in compatible due to different pinout and no SHDN pin. |
| OPA2340UA/2K5 | Higher precision (50 µV VIO max), rail-to-rail I/O, but lower bandwidth (5.5 MHz) and output drive (±20 mA). | Preferred for high-accuracy, low-noise DC signal chains (e.g., medical instrumentation) where speed is less critical. | Choose for sub-100 µV offset and RRO performance; requires layout change - no shutdown function and SO-8 package differs from DGN. |
Compared with TLV2771IDBVR and OPA2340UA/2K5, the TLC070IDGNR uniquely balances 10 MHz bandwidth, ±55 mA drive, and integrated shutdown in an 8-pin MSOP - making it optimal for industrial analog I/O where dynamic range, load capability, and power-state control coexist.

FAQ
What is the operating temperature range for the TLC070IDGNR?
The TLC070IDGNR is specified for operation from −40°C to +125°C, as indicated by the "I" suffix in its part number. This extended industrial temperature range makes it suitable for deployment in harsh environments such as motor control cabinets, outdoor instrumentation, and under-hood automotive subsystems where ambient temperatures exceed commercial limits.
Does the TLC070IDGNR support true rail-to-rail input or output?
The TLC070IDGNR features rail-to-rail input capability (common-mode range from 0.5 V to VDD−0.8 V) but does not provide rail-to-rail output swing. Its output typically swings within 1.5 V of VDD and 0.5 V above GND under 55 mA load - sufficient for most 12 V or 5 V single-supply applications but not for zero-volt-referenced outputs.
How does the shutdown function of the TLC070IDGNR behave during power-up?
The TLC070IDGNR powers up enabled by default: the amplifier begins normal operation as soon as VDD reaches ~2.5 V, regardless of SHDN pin state. To ensure controlled startup, tie SHDN to VDD through a pullup resistor or actively drive it high after power stabilization - the device draws only 125 µA in shutdown, so leakage paths must be minimized.
Can the TLC070IDGNR drive a 600 Ω load at 10 VPP without distortion?
Yes - the TLC070IDGNR delivers 0.005% THD+N at 1 kHz with 8 VPP into 10 kΩ and maintains low distortion into 600 Ω loads due to its ±55 mA output drive and 19 V/µs negative slew rate. At 10 VPP, it operates comfortably within its linear output voltage swing and thermal limits when properly heatsinked via the PowerPAD™.
Is the TLC070IDGNR pin-compatible with other devices in the TLC07x family?
The TLC070IDGNR shares the same 8-pin MSOP (DGN) pinout with TLC071IDGNR and TLC072IDGNR, but functional differences exist: TLC071 lacks shutdown, and TLC072 is dual-channel. Pin compatibility does not imply functional interchangeability - verify SHDN usage, channel count, and gain configuration before substitution.
