Product details
Overview
TLV2780ID from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, low-power industrial applications. It operates from 1.8 V to 3.6 V, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate at 2.7 V, and consumes only 650 µA per channel - enabling high-speed signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2780ID datasheet, TLV2780ID pinout, TLV2780ID application, or TLV2780ID equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, shutdown capability (900 nA quiescent current), rail-to-rail output swing down to 180 mV from rails at 1.8 V, and verified performance with capacitive loads up to 25 pF using recommended RNULL compensation.
Technical Context
The TLV2780ID employs a CMOS input stage with 2.5 pA typical input bias current and supports common-mode input voltage from −0.2 V to VDD + 0.2 V. Its internal architecture enables stable unity-gain operation with phase margin ≥58° into 2 kΩ//25 pF loads, and it features an active shutdown control pin that places the output in high-impedance state while reducing supply current by >99.8%.
Designed for single-supply systems, the device maintains 9 nV/√Hz input voltage noise at 10 kHz and ≤0.45% THD+N at 10 kHz with AV = 100, making it suitable for driving SAR ADCs and precision analog front-ends where low distortion and wide bandwidth are critical under tight power budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - compatible with two-cell Li-ion or NiMH batteries; supports ±0.9 V split supply. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop operation up to ~1 MHz with moderate gain (e.g., AV = 8) in sensor amplification stages. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - supports fast settling of 1-V step signals in <2.4 µs (0.01% error), critical for data acquisition timing. |
| Input Offset Voltage | 3000 µV max (−40°C to 125°C) - ensures DC accuracy in millivolt-level transducer signal chains without trimming. |
| Supply Current per Channel | 650 µA typical - allows integration of multiple channels in space-constrained industrial controllers with minimal thermal impact. |
| Shutdown Current | 900 nA - reduces system standby power by >700×, extending battery life in intermittent-sampling IoT nodes. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in audio and precision measurement paths where noise floor dominates resolution. |
Pinout & Package
The TLV2780ID is packaged in an 8-pin SOIC (D) surface-mount package with standard pin spacing (1.27 mm), rated for industrial temperature operation and RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Rail-to-rail voltage source capable of sourcing/sinking ±10 mA; high-impedance during shutdown. |
| 2 (IN−) | Inverting Input | Differential input node with 2.5 pA bias current; requires short trace routing to minimize parasitic capacitance. |
| 3 (IN+) | Non-inverting Input | Differential input node supporting VICR from −0.2 V to VDD + 0.2 V - enables true single-supply sensing below ground reference. |
| 4 (GND) | Analog Ground | Primary return path for input/output currents; must connect to low-impedance ground plane beneath device. |
| 5 (NC) | No Connection | Internally unconnected; no external tie required - PCB pad may be left floating or grounded per layout best practice. |
| 6 (SHDN) | Shutdown Control | Active-low logic input; pulls low to disable amplifier and reduce IDD to 900 nA; floats or ties high to enable. |
| 7 (VDD) | Positive Supply | Power input accepting 1.8–3.6 V; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling per TI layout guidelines. |
| 8 (NC) | No Connection | Internally unconnected; no external tie required - PCB pad may be left floating or grounded per layout best practice. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 2 µV max VIO; 350 µA IDD; no shutdown pin. | Better DC accuracy for ultra-low-offset requirements; lacks power gating for duty-cycled systems. | Select when offset drift over temperature is the dominant error source and continuous operation is acceptable. |
| TLV9001IDBVR | Lower IDD (60 µA); 1-MHz GBW; rail-to-rail I/O; shutdown pin; 0.5-mV VIO max. | Optimized for ultra-low-power always-on monitoring; insufficient bandwidth for >100-kHz signal paths. | Select when microamp-level quiescent current is mandatory and signal bandwidth stays below 100 kHz. |
Compared with OPA333AIDR and TLV9001IDBVR, the TLV2780ID uniquely balances 8-MHz bandwidth, industrial temperature rating, and active shutdown - making it the only choice among the three for high-fidelity, battery-gated sensor interfaces requiring both speed and thermal robustness.

FAQ
What is the maximum capacitive load the TLV2780ID can drive without instability?
The TLV2780ID is characterized for stable operation with up to 25 pF capacitive load when driving a 2-kΩ resistive load, as confirmed in the datasheet's dynamic performance section. For loads exceeding 10 pF, TI recommends adding a series null resistor (RNULL) between the output and capacitive node to maintain ≥58° phase margin and prevent ringing. This design guideline is validated across the full −40°C to 125°C temperature range for the TLV2780ID.
Does the TLV2780ID support true rail-to-rail input common-mode range?
Yes, the TLV2780ID supports a common-mode input voltage range from −0.2 V to VDD + 0.2 V, which extends 200 mV beyond both supply rails. This allows the device to accurately amplify signals referenced below ground (e.g., in level-shifting or bipolar sensor interfaces) while maintaining rail-to-rail output swing - a capability explicitly specified and tested for the TLV2780ID across its full industrial temperature range.
What is the typical shutdown current of the TLV2780ID, and how quickly does it respond?
The TLV2780ID draws 900 nA typical supply current per channel in shutdown mode (SHDN = 0 V), with a maximum of 1.7 µA over temperature. Its turn-on time is 800 ns and turn-off time is 200 ns, measured from SHDN logic transition to 50% of final supply current - values confirmed in the shutdown characteristics table of the TLV2780ID datasheet for reliable microsecond-scale power gating in burst-mode systems.
Can the TLV2780ID operate from a 3.3-V supply, and what are its output voltage limits at that rail?
Yes, the TLV2780ID is fully specified for operation at 3.3 V (within its 1.8–3.6-V range). At VDD = 3.3 V, the high-level output voltage (VOH) is ≥3.25 V at IOH = −1 mA, and the low-level output voltage (VOL) is ≤50 mV at IOL = 1 mA - confirming true rail-to-rail swing with <100-mV headroom at both extremes, as documented in the output characteristics table for the TLV2780ID.
How does the input offset voltage of the TLV2780ID compare to the TLV2780CD commercial-grade variant?
The TLV2780ID specifies a maximum input offset voltage of 3000 µV over −40°C to 125°C, while the TLV2780CD is rated at 3000 µV over 0°C to 70°C. Both share identical 250-µV typical VIO at 25°C, but the TLV2780ID's tighter full-range specification (vs. CD's wider max at elevated temperature) reflects its qualification for harsh industrial environments - a distinction clearly defined in the "Available Options" table of the TLV2780ID datasheet.
