Product details
Overview
TLV2780CDBVT 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 bandwidth and 4.8 V/µs slew rate at just 650 µA per channel, and supports −0.2 V to VDD+0.2 V common-mode input range - enabling precision signal conditioning in battery-powered sensor front-ends and portable data converters.
For engineers reviewing the TLV2780CDBVT datasheet, TLV2780CDBVT pinout, TLV2780CDBVT application, or TLV2780CDBVT equivalent, key selection criteria include its 650 µA supply current at 1.8 V, shutdown capability (900 nA), SOT-23-6 packaging, and guaranteed performance across 0°C to 70°C commercial temperature range.
Technical Context
The TLV2780CDBVT implements a CMOS input stage with rail-to-rail input common-mode range extending 200 mV 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 integrated shutdown control pin that disables the amplifier and places outputs in high-impedance state.
It achieves 9 nV/√Hz input voltage noise at 10 kHz and 0.055% THD+N at AV = 1, making it suitable for driving high-resolution SAR ADCs and low-distortion audio paths where supply headroom is constrained to two rechargeable cells (±0.9 V 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 NiMH/alkaline cells or single Li-ion cell with LDO dropout margin |
| Bandwidth (GBW) | 8 MHz - supports >1 MSPS sampling in active filter or driver stages preceding 12-bit+ ADCs |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - ensures <2.4 µs settling to 0.01% for 1 VPP step with 10 pF load |
| Supply Current | 650 µA per channel - allows 10+ op-amps on sub-7 mA total analog rail in portable instrumentation |
| Input Offset Voltage | 3000 µV max (0°C to 70°C) - sets DC accuracy limit in 12-bit systems with gain ≤10 |
| Shutdown Current | 900 nA per channel - reduces quiescent power by >700× during idle cycles in duty-cycled sensors |
| Input Noise | 9 nV/√Hz at 10 kHz - preserves SNR in microphone preamps and bridge sensor amplifiers |
Pinout & Package
SOT-23-6 package (DBV) with 1.6 mm × 2.9 mm footprint, 0.95 mm height, and gull-wing leads - compatible with standard pick-and-place and reflow processes for space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail swing; high-impedance when SHDN = low |
| 2 (IN−) | Inverting input | High-impedance CMOS node; requires short trace routing to minimize capacitance |
| 3 (IN+) | Non-inverting input | Rail-to-rail common-mode range (−0.2 V to VDD+0.2 V); accepts signals below ground |
| 4 (GND) | Analog ground reference | Must connect to low-noise ground plane; separate from digital ground if mixed-signal layout |
| 5 (SHDN) | Active-low shutdown control | Pull to GND to disable amplifier; floating or VDD enables operation |
| 6 (VDD) | Positive supply | Accepts 1.8–3.6 V; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling |
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 with 0.1 V headroom |
| Low 650 µA supply current | Permits continuous operation in coin-cell-powered devices for >1 year at 100 µA average system current |
| Integrated shutdown | Reduces supply current to 900 nA and isolates output without external MOSFET or enable logic |
| 8 MHz bandwidth at low power | Supports closed-loop gains up to 8 with stable phase margin into 2 kΩ//25 pF loads |
| Specified for 0°C to 70°C | Guarantees parametric performance in commercial-grade embedded controllers and consumer electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2781CDBVT | Dual-channel version in same SOT-23-6 package; identical specs per channel except no shutdown pin | Used where dual amplification is needed without independent shutdown control | Select TLV2781CDBVT only when second amplifier channel is required and shutdown is unnecessary |
| OPA316IDBVR | Higher 10 MHz GBW, lower 5.5 nV/√Hz noise, but 800 µA supply current and no shutdown function | Preferred for higher-bandwidth, lower-noise precision applications where power budget allows +150 µA/channel | Choose OPA316IDBVR when signal fidelity outweighs battery life requirements and shutdown is not needed |
Compared with TLV2781CDBVT and OPA316IDBVR, the TLV2780CDBVT uniquely balances ultra-low quiescent current, integrated shutdown, and rail-to-rail operation in a single-channel SOT-23-6 package - making it optimal for discrete, power-gated signal paths in portable systems.

FAQ
What is the maximum supply voltage for TLV2780CDBVT?
The absolute maximum supply voltage for TLV2780CDBVT 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 or permanent damage, especially under temperature extremes. The device is rated for split-supply operation down to ±0.9 V, confirming robustness at the lower end of its specified range.
Does TLV2780CDBVT support rail-to-rail input below ground?
Yes, TLV2780CDBVT supports a common-mode input voltage range from −0.2 V to VDD+0.2 V, meaning it accepts inputs 200 mV below ground (GND) when VDD ≥ 1.8 V. This is confirmed in the "recommended operating conditions" table and enables direct interfacing with bipolar sensors or level-shifted signals without external clamping diodes or bias networks.
What is the typical shutdown current of TLV2780CDBVT?
The typical shutdown current of TLV2780CDBVT is 900 nA per channel at 25°C, with a maximum of 1700 nA over the full 0°C to 70°C commercial temperature range. This value is measured with SHDN = 0 V, VDD = 1.8–3.6 V, and is validated in the "shutdown characteristics" section of the datasheet - critical for estimating battery lifetime in intermittently active systems.
Can TLV2780CDBVT drive capacitive loads without instability?
TLV2780CDBVT remains stable with capacitive loads ≤10 pF directly at the output. For loads >10 pF, the datasheet recommends adding a series null resistor (RNULL) between the output and load to preserve phase margin - demonstrated in Figure 30. Without this, ringing or oscillation may occur due to reduced phase margin, especially at higher gains or supply voltages.
What package type does TLV2780CDBVT use and how is it ordered?
TLV2780CDBVT uses the SOT-23-6 (DBV) package, which is only available taped and reeled. The "T" suffix explicitly denotes a 250-piece mini-reel configuration per the ordering information in the datasheet's "Available Options" table. Standard reels contain 3,000 pieces and use the "R" suffix (e.g., TLV2780CDBVR), but TLV2780CDBVT is the correct orderable part number for the 250-piece variant.
