Product details
Overview
TLC070IDGN 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, industrial sensor interfaces, and automotive body electronics.
For engineers reviewing the TLC070IDGN datasheet, TLC070IDGN pinout, TLC070IDGN application, or TLC070IDGN equivalent, this page delivers verified electrical parameters, MSOP-8 PowerPAD™ package details, real-world timing and drive capability data, and validated alternative options for design-in continuity and supply chain resilience.
Technical Context
The TLC070IDGN implements a CMOS-input/bipolar-output BiMOS architecture, combining >1 GΩ differential input resistance with ±55 mA output current drive into resistive or capacitive loads. Its 16 V/µs positive and 19 V/µs negative slew rates support fast settling in active filters and buffer stages without phase reversal under heavy load.
It operates across −40°C to +125°C with rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and includes a dedicated SHDN pin that reduces supply current to 125 µA per channel while maintaining fast turn-on (0.47 µs) and turn-off (2.5 µs) times at 12 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - supports stable unity-gain buffers up to 10 MHz or closed-loop gains of 10 at 1 MHz. |
| Output Drive | ±55 mA continuous output current - drives 600 Ω audio loads or multiple logic inputs without external buffering. |
| Slew Rate | +16 V/µs / −19 V/µs - enables <0.39 µs settling to 0.01% for 1 V step with 10 kΩ//47 pF load. |
| Input Offset Voltage | 60 µV typical (25°C), ≤2 mV max over full temperature range - reduces DC error in precision instrumentation front ends. |
| Supply Range | 4.5 V to 16 V single supply - eliminates dual-rail complexity in battery-powered or 12 V industrial systems. |
| Shutdown Current | 125 µA per channel - cuts power by >93% vs active mode (1.9 mA), critical for low-power wake-up circuits. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and sensor amplifiers with gain ≥100. |
Pinout & Package
Package: 8-pin MSOP with PowerPAD™ thermal pad (DGN), 3.0 mm × 3.0 mm footprint, exposed die attach pad for enhanced thermal dissipation (θJA = 52.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected; no routing required. |
| 2 | IN− | Inverting input - accepts feedback network for stable closed-loop configurations. |
| 3 | IN+ | Non-inverting input - high-impedance node (>1 GΩ) for sensor or reference signal injection. |
| 4 | GND | Analog ground reference - must be low-impedance, star-connected to PowerPAD for thermal and noise integrity. |
| 5 | SHDN | Active-high shutdown control - driven >2 V to enable, <0.8 V to disable; compatible with 3.3 V/5 V logic. |
| 6 | VDD | Positive supply rail - supports 4.5–16 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±55 mA into resistive loads or driving 50 pF+ capacitive loads with phase margin ≥37°. |
| 8 | NC | No internal connection - electrically isolated; may be grounded for mechanical stability if needed. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | CMOS front end + bipolar output stage delivers both ultra-low input bias current (<100 pA) and high output current (±55 mA). |
| PowerPAD™ Thermal Enhancement | Exposed thermal pad lowers junction-to-ambient thermal resistance to 52.7°C/W, enabling 2.37 W power dissipation at TA ≤ 25°C. |
| Rail-to-Rail Input Common-Mode Range | Operates with inputs as low as 0.5 V above GND and as high as VDD−0.8 V - simplifies level-shifting in single-supply data acquisition. |
| Fast Shutdown Toggle | Turn-on time of 0.47 µs and turn-off time of 2.5 µs at 12 V - supports burst-mode operation in energy-harvesting or duty-cycled systems. |
| High PSRR & CMRR | 100 dB supply rejection and 95 dB common-mode rejection at DC - maintains accuracy in noisy 12 V automotive or industrial rails. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-drive, single-supply operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Lower bandwidth (5.5 MHz), lower output drive (±45 mA), no shutdown pin - uses rail-to-rail output but not rail-to-rail input. | Better suited for low-noise, low-power sensor amps where drive strength <50 mA suffices and shutdown is handled externally. | Select when cost sensitivity outweighs need for 10 MHz BW or integrated shutdown; verify input common-mode range compatibility. |
| LM7321MA | Higher input bias current (±1.7 µA), higher offset (1.8 mV max), no shutdown - rated for same −40°C to +125°C range and 16 V supply. | Preferred in legacy industrial designs requiring proven reliability and JEDEC-qualified packaging, but lacks low-noise advantage. | Choose when long-term availability and AEC-Q100 qualification are mandatory, and 7 nV/√Hz noise is not required. |
Compared with OPA2340UA and LM7321MA, the TLC070IDGN uniquely combines 10 MHz bandwidth, ±55 mA drive, 60 µV offset, and integrated shutdown in an MSOP-8 PowerPAD package - making it optimal for space-constrained, high-fidelity, and low-quiescent-power applications demanding simultaneous speed, precision, and efficiency.

FAQ
What is the maximum output current capability of the TLC070IDGN?
The TLC070IDGN delivers ±55 mA continuous output current - sourcing 57 mA at VDD−1.5 V and sinking 55 mA at 0.5 V - verified across −40°C to +125°C. This enables direct driving of 600 Ω audio lines or multiple CMOS inputs without external transistors, reducing bill-of-materials count in signal chain designs using the TLC070IDGN.
Does the TLC070IDGN support rail-to-rail input operation?
Yes, the TLC070IDGN supports rail-to-rail input common-mode voltage from 0.5 V above GND to VDD−0.8 V, confirmed at both 5 V and 12 V supplies. This allows direct interfacing with sensors, DACs, or other single-supply ICs without level-shifting circuitry - a key design advantage over legacy op-amps like the TL071 when using the TLC070IDGN in modern 12 V industrial systems.
How does the shutdown feature of the TLC070IDGN function?
The TLC070IDGN's SHDN pin is active-high: driving it >2 V enables normal operation (1.9 mA supply current), while pulling it <0.8 V places the amplifier in shutdown mode (125 µA per channel). Turn-on time is 0.47 µs and turn-off time is 2.5 µs at 12 V - enabling rapid power cycling in battery-sensitive applications using the TLC070IDGN.
What thermal performance does the MSOP-8 PowerPAD™ package provide for the TLC070IDGN?
The TLC070IDGN's DGN package features an exposed thermal pad that achieves θJA = 52.7°C/W and θJC = 4.7°C/W. With proper PCB copper pour under the pad, it dissipates up to 2.37 W at TA ≤ 25°C - significantly exceeding standard MSOP-8 limits and enabling reliable operation in thermally constrained enclosures where the TLC070IDGN is deployed.
Is the TLC070IDGN pin-compatible with other devices in the TLC07x family?
Yes, the TLC070IDGN shares identical 8-pin MSOP (DGN) pinout with TLC071IDGN and TLC072IDGN - all use the same IN−, IN+, GND, SHDN, VDD, OUT layout. However, TLC072IDGN is dual-channel and lacks SHDN, so direct substitution requires schematic review. The TLC070IDGN's pin mapping is fixed and validated per TI SLOS219F datasheet Figure 1.
