Product details
Overview
TLC070CDGN from Texas Instruments is a single-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V). It features ultralow input offset voltage (60 µV typ), low input noise (7 nV/√Hz), and integrated shutdown functionality - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC070CDGN datasheet, TLC070CDGN pinout, TLC070CDGN application, or TLC070CDGN equivalent, this device is selected for designs requiring rail-to-rail output swing capability, fast settling (<0.39 µs to 0.01%), high slew rate (16 V/µs), and stable operation into capacitive loads up to 100 pF without external compensation.
Technical Context
The TLC070CDGN employs TI's patented LBC3 BiCMOS process, combining a high-impedance CMOS input stage with a bipolar output stage to deliver both low noise and high current drive. Its internal architecture supports true single-supply operation with common-mode input range extending from 0.5 V to VDD − 0.8 V and rail-to-rail output swing under moderate load.
It integrates an active shutdown pin (SHDN) that reduces supply current to 125 µA per channel while maintaining fast enable/disable timing (ton = 0.47 µs, toff = 2.5 µs at VDD = 12 V). Phase margin remains stable (≥37°) across 0–100 pF load capacitance when configured as a unity-gain follower.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable closed-loop operation up to 10× gain at 1 MHz. |
| Slew Rate | +16 V/µs / −19 V/µs - supports clean 10-VPP output at 100 kHz without slewing distortion. |
| Output Drive | ±55 mA continuous - drives 600 Ω audio loads or multiple CMOS inputs directly without buffer stages. |
| Input Offset Voltage | 60 µV typical (25°C) - minimizes DC error in precision transducer amplification and DAC output buffering. |
| Supply Range | 4.5 V to 16 V single supply - operates from 5 V logic rails or 12 V industrial buses without dual supplies. |
| Shutdown Current | 125 µA per channel - reduces system standby power in battery-powered instrumentation and portable test gear. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamps and strain-gauge signal chains. |
Pinout & Package
Package: 8-pin MSOP PowerPAD™ (DGN) with exposed thermal pad for enhanced power dissipation (θJA = 52.7°C/W, max power rating 2.37 W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pin; may be left floating or tied to GND for mechanical stability. |
| 2 | IN− | Inverting input - accepts feedback network for stable closed-loop configurations including inverting amplifiers. |
| 3 | IN+ | Non-inverting input - used for unity-gain buffers, active filters, and sensor differential amplification. |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane to minimize noise coupling. |
| 5 | SHDN | Active-high shutdown control - logic high (>2 V) enables amplifier; logic low (<0.8 V) disables output and reduces IDD to 125 µA. |
| 6 | VDD | Positive supply rail - accepts 4.5–16 V; requires local 0.1 µF ceramic decoupling capacitor near pin. |
| 7 | OUT | Amplifier output - delivers rail-to-rail swing into ≥600 Ω loads; stable with up to 100 pF capacitive load. |
| 8 | NULL | No internal connection - unused pin; no electrical function; may be left unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input (1 TΩ input impedance) with bipolar output (±55 mA drive) - eliminates need for discrete output buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2771CDGN | Lower bandwidth (2 MHz), lower output drive (±25 mA), but rail-to-rail input/output and lower quiescent current (1.2 mA). | Better suited for ultra-low-power battery sensing; insufficient for 600 Ω audio loads or fast settling demands. | Select TLV2771CDGN only if power budget <1.5 mA/channel is critical and bandwidth ≤2 MHz suffices. |
| OPA2350UA/2K5 | Higher precision (5 µV offset), lower noise (5.5 nV/√Hz), but no shutdown pin and limited output drive (±30 mA). | Preferred for high-resolution data acquisition where offset drift dominates; lacks power-gating capability for intermittent operation. | Choose OPA2350UA/2K5 when sub-10 µV offset and <0.001% THD+N are mandatory, and shutdown is not required. |
Compared with TLV2771CDGN and OPA2350UA/2K5, the TLC070CDGN uniquely balances wide bandwidth, high output current, and integrated shutdown - making it optimal for industrial analog output stages where dynamic power control and load-driving capability are jointly essential.

FAQ
What is the maximum capacitive load the TLC070CDGN can drive stably?
The TLC070CDGN maintains phase margin ≥37° with up to 100 pF capacitive load when configured as a unity-gain follower (RL = 10 kΩ, VDD = 12 V). For loads >100 pF, external isolation resistor (e.g., 50 Ω in series with output) is recommended to preserve stability. This capability eliminates need for external compensation in most line-driver and DAC-buffer applications.
Does the TLC070CDGN support rail-to-rail input operation?
No - the TLC070CDGN has a common-mode input voltage range of 0.5 V to VDD − 0.8 V. It does not include rail-to-rail input circuitry. However, its 0.5 V lower bound allows direct interfacing with 0–5 V or 0–12 V sensor outputs without level-shifting, and its VDD − 0.8 V upper limit ensures compatibility with standard single-supply configurations.
How does the shutdown feature affect output state in the TLC070CDGN?
When SHDN is pulled low (<0.8 V), the TLC070CDGN disables its output stage and places the OUT pin in high-impedance state - not clamped or shorted. This allows safe multiplexing of multiple amplifiers onto shared signal paths. Supply current drops to 125 µA per channel, and turn-off time is 2.5 µs (VDD = 12 V), enabling rapid power cycling in time-sliced measurement systems.
Can the TLC070CDGN operate from a 3.3 V supply?
No - the absolute minimum supply voltage for the TLC070CDGN is 4.5 V, as specified in the Recommended Operating Conditions table. Operation below 4.5 V risks degraded AC performance (bandwidth, slew rate), increased input offset voltage, and potential instability. For 3.3 V systems, consider TI's TLV2771 or OPA333 families instead.
What thermal considerations apply to the TLC070CDGN in MSOP PowerPAD™ package?
The TLC070CDGN in DGN package achieves θJA = 52.7°C/W with standard JEDEC 2-layer board layout. Its exposed thermal pad must be soldered to a minimum 100 mm² copper pour for rated 2.37 W power dissipation at TA ≤ 25°C. Without thermal pad connection, θJA degrades to >100°C/W, limiting usable output current in continuous operation.
