Product details
Overview
TLC070CDGNR 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 interfaces, and industrial analog front-ends.
For engineers reviewing the TLC070CDGNR datasheet, TLC070CDGNR pinout, TLC070CDGNR application, or TLC070CDGNR equivalent, this page delivers verified electrical specs, MSOP-8 PowerPAD™ package details, real-world timing and drive capability data, and validated alternative op-amps for design-in and supply continuity planning.
Technical Context
The TLC070CDGNR employs TI's patented LBC3 BiCMOS process, combining a CMOS input stage (1000 GΩ differential input resistance, 700 pA max input bias current) with a bipolar output stage capable of sourcing 57 mA and sinking 55 mA into heavy loads. Its 16 V/µs positive and 19 V/µs negative slew rate supports fast settling (0.18 µs to 0.1%) under 10 kΩ/47 pF conditions.
It operates across 0°C to 70°C (C-suffix), supports rail-to-rail output swing within 0.5 V of rails, and includes dedicated SHDN pin for ultralow-power mode (125 µA/channel). Input common-mode range extends from 0.5 V to VDD − 0.8 V, making it suitable for direct interfacing with microcontroller ADCs and DACs in single-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable unity-gain buffer or 10× amplification up to 1 MHz. |
| Output Drive | ±55 mA continuous output current - drives 600 Ω audio loads or multiple logic inputs without external buffers. |
| Slew Rate | +16 V/µs / −19 V/µs - ensures <0.39 µs settling to 0.01% for 1 V step, critical for pulse and video applications. |
| Input Offset Voltage | 60 µV typical (max 1400 µV) - reduces DC error in precision instrumentation and sensor signal chains. |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V, 12 V, and battery-powered industrial systems. |
| Shutdown Current | 125 µA per channel - enables power gating in portable or energy-sensitive designs. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level audio and medical sensor amplification stages. |
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 performance (θJA = 52.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pin; may be left floating or grounded for mechanical stability. |
| 2 | IN− | Inverting input - high-impedance CMOS node (1000 GΩ) for feedback network attachment. |
| 3 | IN+ | Non-inverting input - accepts common-mode signals from 0.5 V to VDD − 0.8 V. |
| 4 | GND | Analog ground reference - must be low-impedance return path for input/output currents and PowerPAD. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDGNR | Lower bandwidth (6.4 MHz), lower output drive (±15 mA), no shutdown pin, 2.7–6 V supply only. | Better suited for low-voltage, low-power sensor amps where 55 mA drive is unnecessary. | Select TLV2461CDGNR when operating below 5 V or when shutdown functionality is not required. |
| OPA2350UA/2K5 | Higher precision (50 µV VIO, 0.1 µV/°C), rail-to-rail I/O, but lower output drive (±30 mA) and no shutdown. | Ideal for ultra-low-offset applications like medical ECG front-ends where drive strength is secondary. | Choose OPA2350UA/2K5 when sub-100 µV offset and rail-to-rail input/output are mandatory, and load current ≤30 mA. |
Compared with TLV2461CDGNR and OPA2350UA/2K5, the TLC070CDGNR uniquely balances wide bandwidth, high output current, and integrated shutdown in an MSOP-8 PowerPAD™ package - making it the optimal choice for industrial analog output stages and audio line drivers requiring robust drive capability and thermal efficiency.

FAQ
What is the maximum output current capability of the TLC070CDGNR?
The TLC070CDGNR delivers ±55 mA continuous output current - 57 mA sourcing (VOH at VDD − 1.5 V) and 55 mA sinking (VOL at 0.5 V) - verified at 25°C with VDD = 5 V or 12 V. This enables direct drive of 600 Ω audio loads or multiple logic inputs without external buffering, and is supported by its MSOP PowerPAD™ thermal design (θJA = 52.7°C/W).
Does the TLC070CDGNR support true single-supply operation with rail-to-rail input?
The TLC070CDGNR supports single-supply operation from 4.5 V to 16 V, but its input common-mode range is specified from 0.5 V to VDD − 0.8 V - not rail-to-rail. It does provide rail-to-rail output swing (within 0.5 V of each rail). For full rail-to-rail input, consider alternatives like the OPA2350UA/2K5, but note that TLC070CDGNR maintains superior output drive and bandwidth in its specified input range.
How does the shutdown feature of the TLC070CDGNR operate?
The TLC070CDGNR's SHDN pin is active-high: applying ≥2 V enables normal operation; ≤0.8 V places the device in ultralow-power shutdown mode, reducing supply current to 125 µA per channel. Turn-on and turn-off times are 0.15 µs and 1.3 µs respectively - defined as the interval for supply current to reach 50% of final value. The pin is CMOS-compatible and requires no external pull-up/down resistors.
What thermal performance can be expected from the TLC070CDGNR in its MSOP PowerPAD™ package?
The TLC070CDGNR in the DGN (MSOP PowerPAD™) package achieves θJA = 52.7°C/W and θJC = 4.7°C/W. With proper PCB layout (exposed thermal pad soldered to ≥1 cm² copper pour), it dissipates up to 2.37 W at TA ≤ 25°C - significantly higher than standard SOIC or PDIP packages. This enables sustained ±55 mA output drive without thermal derating in compact industrial designs.
Is the TLC070CDGNR pin-compatible with other devices in the TLC07x family?
The TLC070CDGNR (single-channel, 8-pin MSOP) shares identical pinout with TLC071CDGNR and TLC072CDGNR (dual-channel, same package), but differs from TLC073 (10-pin DGQ) and TLC074/75 (14-/16-pin TSSOP/PDIP). Pin compatibility is confirmed only among DGN-packaged single/dual variants - TLC070CDGNR and TLC071CDGNR use identical pin 1–8 assignments (NULL, IN−, IN+, GND, SHDN, VDD, OUT, NULL).
