Product details
Overview
TLV2780CDBVR 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 sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2780CDBVR datasheet, TLV2780CDBVR pinout, TLV2780CDBVR application, or TLV2780CDBVR equivalent, key selection criteria include its 1.8 V minimum supply, −0.2 V to VDD+0.2 V common-mode input range, 9 nV/√Hz input noise at 10 kHz, shutdown capability (900 nA quiescent current), and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2780CDBVR implements a CMOS input stage with rail-to-rail input common-mode range extending 0.2 V beyond both supply rails and rail-to-rail output swing. Its internal architecture supports stable unity-gain operation with 58° phase margin into 2 kΩ || 25 pF loads, and features an active shutdown terminal (Pin 5) that places the amplifier in high-impedance state while reducing supply current to sub-µA levels.
Designed for single-supply operation, it achieves 8 MHz bandwidth with only 650 µA supply current per channel - a power-bandwidth efficiency of 12.3 MHz/mA - and maintains 0.055% THD+N at 10 kHz with AV = 1, making it suitable for driving SAR ADC front-ends and audio line drivers where distortion and noise are critical.
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 closed-loop gains up to 8× at 1 MHz or unity gain at 8 MHz for fast settling in data converter buffers. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - ensures ≤2.4 µs 0.01% settling for 1 VPP steps, critical for multiplexed ADC sampling. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in precision sensor amplification chains before digitization. |
| Supply Current per Channel | 650 µA - allows integration of multiple channels in ultra-low-power IoT nodes without thermal penalty. |
| Shutdown Current | 900 nA - reduces system standby power by >700×, extending battery life in duty-cycled measurement systems. |
| Common-Mode Input Range | −0.2 V to VDD + 0.2 V - accepts inputs below ground or above VDD, simplifying level-shifting in mixed-supply systems. |
Pinout & Package
SOT-23-5 (DBV) package: 5-pin, ultrasmall surface-mount plastic package with 0.95 mm pitch, 2.9 mm × 1.6 mm footprint, and exposed pad not present - compatible with standard reflow profiles and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Delivers rail-to-rail voltage swing; drives 2 kΩ load with <290 mV VOL at 5 mA sink. |
| 2 (IN−) | Inverting Input | High-impedance CMOS node; requires short trace routing to minimize stray capacitance and oscillation risk. |
| 3 (IN+) | Non-Inverting Input | Accepts signals from −0.2 V to VDD+0.2 V; enables true single-supply transducer interfacing. |
| 4 (GND) | Analog Ground Reference | Primary return path for input bias currents and output load current; must connect to clean analog ground plane. |
| 5 (SHDN) | Active-Low Shutdown Control | Pulled low disables amplifier and forces output to high-Z; floating or pulled high enables normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail I/O | Enables full dynamic range utilization in 1.8 V systems - e.g., 0–1.8 V output swing preserves 12-bit ADC resolution without level-shifting. |
| 1.8 V Minimum Supply | Eliminates need for LDO regulators in coin-cell or dual-cell designs, reducing BOM count and PCB area. |
| 8 MHz Bandwidth @ 650 µA | Provides 12.3 MHz/mA efficiency - 3× higher than comparable micropower op-amps - for real-time sensor signal processing. |
| Shutdown Mode (900 nA) | Allows time-sliced operation in battery-powered data loggers, cutting average current to sub-µA during idle intervals. |
| Low 9 nV/√Hz Input Noise | Minimizes added noise in front-end amplification of thermocouples or strain gauges, preserving system-level ENOB. |

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 but rated for −40°C to 125°C industrial temperature range vs. 0°C to 70°C for TLV2780CDBVR. | Required for automotive under-hood or industrial motor control environments exceeding 70°C ambient. | Select TLV2780IDBVR when extended temperature operation is mandatory; otherwise TLV2780CDBVR suffices for commercial indoor applications. |
| OPA333AIDBVR | Zero-drift architecture (0.1 µV/°C offset drift), lower 0.6 µV max VIO, but higher 17 µA supply current and 350 kHz GBW. | Better DC precision for weigh scales or medical diagnostics; unsuitable for >100 kHz signal paths due to limited bandwidth. | Choose OPA333AIDBVR only when microvolt-level DC accuracy dominates over speed and power; TLV2780CDBVR remains optimal for AC-coupled, bandwidth-sensitive designs. |
Compared with TLV2780IDBVR, the TLV2780CDBVR trades extended temperature range for lower cost and qualification scope; versus OPA333AIDBVR, it delivers 23× higher bandwidth per µA but sacrifices sub-microvolt DC stability - making TLV2780CDBVR the preferred choice for portable, battery-operated, medium-speed signal chains.

FAQ
What is the maximum recommended supply voltage for TLV2780CDBVR?
The absolute maximum supply voltage for TLV2780CDBVR 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 is fully characterized and supports rail-to-rail output swing up to 3.55 V at 5 mA load.
Does TLV2780CDBVR support true rail-to-rail input operation?
Yes, TLV2780CDBVR supports true rail-to-rail input operation with a common-mode input voltage range of −0.2 V to VDD + 0.2 V. This allows input signals to extend 200 mV below ground or 200 mV above VDD, enabling direct interfacing with transducers that output negative offsets or exceed the supply rail.
How does the shutdown function behave on TLV2780CDBVR?
When Pin 5 (SHDN) is pulled low (≤0.6 V), TLV2780CDBVR enters shutdown mode with supply current reduced to 900 nA typical and output placed in high-impedance state. The amplifier resumes normal operation when SHDN is left floating or pulled high (≥2 V); parasitic leakage must be managed to prevent unintended shutdown.
What is the typical input offset voltage for TLV2780CDBVR at 25°C?
The typical input offset voltage for TLV2780CDBVR at 25°C is 250 µV, with a maximum of 3000 µV over the 0°C to 70°C commercial temperature range. This value is specified for the C-suffix grade and reflects the device's performance without trimming - sufficient for most medium-precision signal conditioning tasks.
Can TLV2780CDBVR drive capacitive loads without external compensation?
TLV2780CDBVR is stable for capacitive loads ≤10 pF with no external compensation. For loads >10 pF, a series resistor (RNULL) must be added between the output and load to maintain phase margin - e.g., 10 Ω for 100 pF - as detailed in Figure 30 of the SLOS245E datasheet to prevent ringing or oscillation.
