Product details
Overview
TLV2780IDBVR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for ultra-low-voltage operation (1.8 V to 3.6 V), delivering 8 MHz gain-bandwidth product and 4.8 V/µs slew rate at only 650 µA per channel. It features shutdown capability, −40°C to +125°C industrial temperature range, and ultrasmall SOT-23-6 packaging-ideal for battery-powered instrumentation and high-resolution data acquisition front-ends.
For engineers reviewing the TLV2780IDBVR datasheet, TLV2780IDBVR pinout, TLV2780IDBVR application, or TLV2780IDBVR equivalent, key selection criteria include its sub-2-V minimum supply, rail-to-rail I/O swing, low 9 nV/√Hz input noise at 10 kHz, shutdown current of <1.7 µA, and guaranteed performance across extended industrial temperature range without derating.
Technical Context
The TLV2780IDBVR implements a CMOS input stage with rail-to-rail common-mode input range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing, enabling full dynamic range utilization in single-supply systems. Its internal architecture supports stable unity-gain operation into 2 kΩ loads with 10 pF capacitive load, achieving 58° phase margin and 8 dB gain margin.
Shutdown control is active-low on Pin 5 (SHDN), reducing supply current to ≤1.7 µA per channel while placing the output in high-impedance state. The device maintains specified AC performance-including 8 MHz GBW and 4.8 V/µs positive slew rate-at VDD = 2.7 V and TA = 25°C, with monotonic degradation down to 1.8 V.
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; eliminates need for voltage regulators in portable designs. |
| Gain-Bandwidth Product | 8 MHz - Supports stable closed-loop gain ≥10 up to ~800 kHz; sufficient for anti-aliasing filters and fast-settling ADC drivers. |
| Slew Rate | 4.8 V/µs (positive), 2.8 V/µs (negative) at VDD = 2.7 V - Enables 1-VPP output step settling in ≤2.4 µs (0.01%) for precision signal conditioning. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - Low-noise performance critical for amplifying µV-level sensor outputs without degrading SNR. |
| Input Offset Voltage | Max 3000 µV over −40°C to +125°C - Matches precision requirements of 12-bit to 14-bit data converters without trimming. |
| Shutdown Current | ≤1700 nA per channel - Reduces system standby power by >99% versus active mode (650 µA), extending battery life in intermittent-sampling applications. |
| Rail-to-Rail I/O | Input range: −0.2 V to VDD+0.2 V; Output swing: within 180 mV of rails at 1 mA - Maximizes usable signal headroom in low-voltage systems. |
Pinout & Package
SOT-23-6 package: 2.9 mm × 1.6 mm × 1.1 mm body, gull-wing leads, JEDEC MO-178AC compliant. Thermal resistance θJA = 294.3°C/W (standard PCB), θJC = 55°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; drives 2 kΩ loads with <1.8% THD+N at 10 kHz. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; bias current ≤300 pA enables high-Z sensor interfaces. |
| 3 (IN+) | Non-inverting input | Common-mode range extends 0.2 V beyond rails-supports input signals below ground or above VDD. |
| 4 (GND) | Analog ground reference | Single ground connection; requires low-inductance layout to minimize PSRR degradation. |
| 5 (SHDN) | Active-low shutdown control | Pulled low disables amplifier and forces output high-Z; floating or pulled high enables operation. |
| 6 (VDD) | Positive supply | Accepts 1.8–3.6 V; decoupling with 0.1 µF ceramic capacitor within 2.5 mm is mandatory for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply voltage | Operates down to 1.8 V-enables direct interface with 1.8-V logic and energy-harvesting sources. |
| Rail-to-rail input/output | Full input range (−0.2 V to VDD+0.2 V) and output swing (within 180 mV of rails) maximize dynamic range in single-supply systems. |

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 no shutdown; VDD min = 1.8 V, max = 5.5 V. | Lacks shutdown function-unsuitable for battery-cycled systems requiring ultra-low standby current. | Select when higher speed/noise performance is prioritized over power gating capability. |
| TLV9001IDBVR | Lower supply current (60 µA), rail-to-rail I/O, but GBW = 1 MHz and VDD min = 1.8 V; no shutdown pin. | Insufficient bandwidth for fast-settling ADC drivers; lacks shutdown for low-power modes. | Choose for always-on, low-quiescent applications where 1-MHz bandwidth suffices. |
Compared with OPA316IDBVR and TLV9001IDBVR, the TLV2780IDBVR uniquely combines 8-MHz bandwidth, rail-to-rail I/O, and integrated shutdown in a 6-pin SOT-23 package-making it the only option among the three that meets simultaneous requirements for high-speed, low-voltage, and ultra-low-power operation.

FAQ
What is the maximum recommended supply voltage for TLV2780IDBVR?
The absolute maximum supply voltage for TLV2780IDBVR 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 degradation and reduced reliability; operation at 3.6 V delivers optimal slew rate (4–5 V/µs) and output drive capability while maintaining rail-to-rail functionality.
Does TLV2780IDBVR support true rail-to-rail input at 1.8-V supply?
Yes, TLV2780IDBVR supports rail-to-rail input with a common-mode range of −0.2 V to VDD + 0.2 V across its full supply range. At VDD = 1.8 V, this means inputs can be as low as −0.2 V and as high as 2.0 V-enabling direct interfacing with signals referenced below ground or exceeding the supply rail, critical for sensor biasing and level-shifting.
How does the shutdown function behave on TLV2780IDBVR?
When Pin 5 (SHDN) is pulled low, TLV2780IDBVR enters shutdown mode with supply current ≤1700 nA per channel and output placed in high-impedance state. To enable, SHDN must be left floating or pulled high to VDD. Parasitic leakage must be controlled-TI recommends a pull-up resistor ≤100 kΩ if floating is not assured-to prevent unintended shutdown during operation.
What is the typical input offset voltage drift over temperature for TLV2780IDBVR?
The temperature coefficient of input offset voltage (αVIO) for TLV2780IDBVR is 8 µV/°C maximum. Over the −40°C to +125°C range, this results in ≤1320 µV additional offset drift beyond the 2000 µV max at 25°C for the 'A' grade, yielding a worst-case total VIO of 3320 µV-still within specification limits for 12-bit accuracy in most industrial sensor applications.
Can TLV2780IDBVR drive a 10-nF capacitive load stably?
No-TLV2780IDBVR is characterized for stability with ≤10 pF capacitive load. Driving 10 nF (10,000 pF) directly will cause severe peaking or oscillation due to phase margin collapse. TI recommends adding a series isolation resistor (RNULL) between the output and the load, sized per application notes (e.g., 10–100 Ω), to restore stability while accepting minor bandwidth reduction.
