Product details
Overview
TLV2780IDBVT 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 data converters and portable instrumentation.
For engineers reviewing the TLV2780IDBVT datasheet, TLV2780IDBVT pinout, TLV2780IDBVT application, or TLV2780IDBVT equivalent, this page provides verified electrical specifications, SOT-23-5 package terminal mapping, industrial-grade (−40°C to 125°C) performance data, and validated alternative op-amps for precision analog front-ends requiring rail-to-rail swing and sub-1-mA quiescent current.
Technical Context
The TLV2780IDBVT employs a CMOS input stage with p-channel and n-channel differential pairs to achieve rail-to-rail input common-mode range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its unity-gain-stable architecture supports capacitive loads up to 25 pF with ≥58° phase margin when RNULL = 0 Ω and RL = 2 kΩ.
It integrates an active shutdown function (SHDN pin) that reduces supply current to ≤1.7 µA per channel while placing the output in high-impedance state - critical for power-gated sensor interfaces and multi-channel systems where channel-by-channel enable/disable is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - enables direct operation from two alkaline or NiMH cells without regulation. |
| Gain-Bandwidth Product | 8 MHz - supports >1-MSPS SAR ADC driving and anti-aliasing filter design up to ~1 MHz. |
| 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 buffer stages. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - low enough for 16-bit precision signal chains with <1 LSB noise contribution at 100-kHz bandwidth. |
| Supply Current per Channel | 650 µA typical - allows 10+ channels on a 10-mA system rail, ideal for multi-sensor IoT nodes. |
| Input Offset Voltage | 3000 µV max over −40°C to 125°C - specified for industrial temperature range, not just commercial grade. |
| Shutdown Current | ≤1700 nA per channel - reduces standby power by >380× vs active mode, extending battery life in sleep cycles. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.1 mm body, gull-wing leads, RoHS-compliant, tape-and-reel (3000 pcs/reel). Thermal resistance θJA = 324.1°C/W; maximum power dissipation at TA = 25°C is 385 mW.
| 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 node for feedback configuration; low input bias current (2.5 pA typ) minimizes offset error in high-Z networks. |
| 3 (IN+) | Non-inverting Input | High-impedance node supporting rail-to-rail common-mode range; matched to IN− for optimal CMRR. |
| 4 (GND) | Analog Ground | Reference return for all internal circuitry; must be connected to low-noise system ground plane. |
| 5 (SHDN) | Shutdown Control | Active-low logic input: <0.6 V disables amplifier; >2 V or floating enables it; no pull-up required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8-V systems - output swings within 180 mV of rails at 1-mA load. |
| Industrial temp range | Specified from −40°C to +125°C - qualified for under-hood automotive sensors and industrial PLC I/O modules. |
| Low-noise CMOS input | 9 nV/√Hz input voltage noise at 10 kHz - preserves SNR in microphone preamps and strain-gauge amplifiers. |
| Shutdown control | Reduces IDD to ≤1.7 µA per channel - allows dynamic power scaling in multi-op-amp data acquisition systems. |
| Unity-gain stable | Operates stably with CL ≤ 25 pF and RL = 2 kΩ - eliminates need for external compensation in most buffer designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher GBW (10 MHz), lower noise (5.5 nV/√Hz), but higher supply current (400 µA vs 650 µA at 1.8 V). | Preferred for higher-bandwidth audio or faster ADC drivers; less suitable for ultra-low-power wake-on-event sensing. | Select OPA316IDBVR when bandwidth >8 MHz or noise <7 nV/√Hz is required, and supply current budget allows ≥400 µA. |
| TLV9001IDBVR | Lower VIO (0.75 mV max), rail-to-rail I/O, but slower slew rate (2 V/µs) and lower GBW (1 MHz). | Better for DC-precision applications like weigh scales; insufficient for >100-kHz signal paths. | Choose TLV9001IDBVR when offset-critical DC accuracy dominates over speed, and 1-MHz bandwidth suffices. |
Compared with TLV2780IDBVT, OPA316IDBVR trades higher speed and lower noise for reduced power efficiency, while TLV9001IDBVR sacrifices bandwidth and slew rate to achieve microvolt-level offset stability - making TLV2780IDBVT the balanced choice for industrial mixed-signal systems needing both speed and low quiescent current.

FAQ
What is the maximum recommended supply voltage for TLV2780IDBVT?
The absolute maximum supply voltage for TLV2780IDBVT is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V per the datasheet. Exceeding 3.6 V risks parametric shift and reliability degradation, especially at high temperature. Operation at 3.6 V is fully characterized and supports rail-to-rail output swing with 4.8 V/µs slew rate.
Does TLV2780IDBVT support true rail-to-rail input common-mode range?
Yes, TLV2780IDBVT supports a common-mode input voltage range from −0.2 V to VDD + 0.2 V, verified across the full −40°C to 125°C industrial temperature range. This allows direct interfacing with sensors or DACs operating near ground or near VDD without level-shifting circuitry.
How does the shutdown function behave on TLV2780IDBVT?
When SHDN (Pin 5) is pulled below 0.6 V, TLV2780IDBVT enters shutdown mode with supply current ≤1700 nA per channel and output placed in high-impedance state. The amplifier resumes normal operation within 800 ns after SHDN rises above 2 V. No external pull-up resistor is required - floating SHDN defaults to enabled.
Can TLV2780IDBVT drive a 10-pF capacitive load without oscillation?
Yes, TLV2780IDBVT is unity-gain stable and characterized to drive up to 25-pF capacitive loads with ≥58° phase margin when RL = 2 kΩ. For loads >10 pF, TI recommends adding a small series resistor (RNULL) between the output and load to maintain stability - a standard practice confirmed in Figure 30 of the TLV2780IDBVT datasheet.
What is the input offset voltage specification for TLV2780IDBVT over temperature?
TLV2780IDBVT has a maximum input offset voltage of 3000 µV over the full industrial temperature range (−40°C to 125°C), with a typical value of 250 µV at 25°C. Its temperature coefficient is 8 µV/°C, meaning offset drift contributes ≤0.8 mV over a 100°C span - critical for uncalibrated industrial sensor interfaces.
