Product details
Overview
TLV2780IDG4 from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, low-power 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 draws only 650 µA per channel - enabling high-speed signal conditioning in battery-powered industrial sensors and portable data acquisition systems.
For engineers reviewing the TLV2780IDG4 datasheet, TLV2780IDG4 pinout, TLV2780IDG4 application, or TLV2780IDG4 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.
Technical Context
The TLV2780IDG4 uses 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.
It integrates an active shutdown function tied to Pin 5 (SHDN), which disables the amplifier and places the output in high-impedance state when driven low - critical for power gating in multi-stage analog front-ends.
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; avoids need for LDO regulation in compact portable designs. |
| Gain-Bandwidth Product | 8 MHz - supports >1 MSPS sampling in driving SAR ADCs without bandwidth limiting. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - ensures <2.4 µs settling to 0.01% for 1 V step, suitable for fast-settling sensor interfaces. |
| Input Offset Voltage | 3000 µV max (−40°C to 125°C) - enables DC-coupled amplification of mV-level transducer outputs with minimal calibration overhead. |
| Supply Current per Channel | 650 µA typical - allows integration of multiple channels in ultra-low-power IoT edge nodes with sub-1 mA total analog subsystem current. |
| Shutdown Current | 900 nA - reduces standby power by >700× versus active mode, extending battery life in duty-cycled measurement systems. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in precision signal chains handling audio-band or vibration-sensor signals. |
Pinout & Package
The TLV2780IDG4 is housed in a 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement. Pin 1 is output (OUT), Pin 2 is inverting input (IN−), Pin 3 is non-inverting input (IN+), Pin 4 is ground (GND), and Pin 5 is shutdown control (SHDN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Rail-to-rail swing (180 mV from rails at 1.8 V); high-impedance during shutdown. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; requires short trace routing to minimize noise pickup and parasitic capacitance. |
| 3 (IN+) | Non-inverting input | Supports VICR from −0.2 V to VDD+0.2 V - enables level-shifting and single-supply sensor biasing. |
| 4 (GND) | Analog ground reference | Must connect to low-impedance ground plane; shared with power supply return for stability. |
| 5 (SHDN) | Active-low shutdown enable | Pulled high (≥2 V) to enable; driven low (≤0.6 V) to disable; floating allowed but not recommended due to leakage risk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization with 1.8 V supply - eliminates headroom loss in low-voltage data converters. |
| Industrial temperature range | Specified from −40°C to 125°C - qualified for under-hood automotive sensors and factory-floor industrial controllers. |
| Low-noise CMOS input | 9 nV/√Hz input voltage noise at 10 kHz - maintains signal integrity in high-gain stages for strain gauge or thermopile amplifiers. |
| Capacitive load drive | Stable with 25 pF load (phase margin ≥58°) - simplifies anti-alias filter design without external isolation resistors. |
| Shutdown mode | 900 nA supply current and high-Z output - permits dynamic power management in multi-channel sensor arrays. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2780IDBVR | Same electrical specs; SOT-23-5 package with tape-and-reel delivery (3000 pcs/reel). | No functional difference; intended for automated SMT assembly rather than manual prototyping. | Select TLV2780IDBVR for volume production; TLV2780IDG4 is tube-packaged for evaluation and low-volume builds. |
| OPA333AIDBVR | Zero-drift architecture; 10 µV max VIO vs 3000 µV; higher 350 µA supply current; no shutdown pin. | Better DC accuracy for precision instrumentation; lacks power-gating capability required in duty-cycled IoT nodes. | Choose OPA333AIDBVR only when offset drift dominates system error budget; TLV2780IDG4 preferred where power efficiency and shutdown are mandatory. |
Compared with TLV2780IDBVR, TLV2780IDG4 offers identical performance in a tube package for flexibility in small-batch development; versus OPA333AIDBVR, it trades DC precision for 1.8× lower supply current and integrated shutdown - making it optimal for battery-constrained, wide-temperature industrial sensing.

FAQ
What is the maximum capacitive load the TLV2780IDG4 can drive while maintaining stability?
The TLV2780IDG4 is characterized for stable operation with up to 25 pF capacitive load at unity gain (RL = 2 kΩ), delivering ≥58° phase margin per the datasheet Figure 18. For loads exceeding 10 pF, TI recommends adding a series null resistor (RNULL) between the output and load to preserve phase margin - a standard practice confirmed in the "Driving a Capacitive Load" section of the TLV2780IDG4 datasheet.
Does the TLV2780IDG4 support true rail-to-rail input common-mode range?
Yes, the TLV2780IDG4 supports a common-mode input voltage range from −0.2 V to VDD+0.2 V, verified across its full −40°C to 125°C operating temperature range. This extends beyond the supply rails, enabling accurate amplification of signals referenced below ground or above VDD - such as bridge sensor outputs or level-shifted interface signals - without clipping or distortion.
What is the typical turn-on time for the TLV2780IDG4 after asserting the SHDN pin high?
The TLV2780IDG4 has a typical amplifier turn-on time (t(on)) of 800 ns when transitioning from shutdown to active mode, measured at the point where supply current reaches 50% of its final value. This fast wake-up enables responsive power cycling in time-critical sensor sampling sequences, and is specified under RL = 2 kΩ load conditions per the Electrical Characteristics table on page 7 of the TLV2780IDG4 datasheet.
Can the TLV2780IDG4 be used with a 1.5 V supply?
No, the TLV2780IDG4 is not rated for operation at 1.5 V. Its absolute minimum supply voltage is 1.8 V, and all specifications - including rail-to-rail output swing, 8 MHz bandwidth, and 4.8 V/µs slew rate - are guaranteed only within the 1.8 V to 3.6 V range. Operating below 1.8 V may result in undefined behavior, reduced gain, or failure to meet AC/DC performance parameters.
Is the TLV2780IDG4 pin-compatible with other devices in the TLV278x family?
Yes, the TLV2780IDG4 shares identical pinout and footprint with all TLV278x variants in the SOT-23-5 (DBV) package, including TLV2780CDG4, TLV2780AIDG4, and TLV2781IDG4. This allows drop-in replacement for different grade or offset-voltage versions without PCB redesign - provided the application does not rely on features unique to dual/quad variants (e.g., shared shutdown lines).
