Product details
Overview
TLV2780AIDR from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for ultra-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 TLV2780AIDR datasheet, TLV2780AIDR pinout, TLV2780AIDR application, or TLV2780AIDR equivalent, this page provides verified electrical parameters, industrial-grade (−40°C to 125°C) thermal performance, shutdown functionality, and real-world design context for precision analog front-ends in space-constrained systems.
Technical Context
The TLV2780AIDR implements a CMOS input stage with rail-to-rail input common-mode range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing, supporting operation down to 1.8 V supply while maintaining 8 MHz bandwidth. Its shutdown pin enables <1.7 µA total quiescent current in disabled state, making it suitable for intermittent-sampling architectures.
It features low input bias current (2.5 pA typ), low input offset voltage (250 µV max at 25°C, 3000 µV over full −40°C to 125°C range), and 9 nV/√Hz input voltage noise at 10 kHz - key for driving SAR ADCs and low-noise sensor interfaces without degrading SNR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports single-cell Li-ion or dual NiMH battery operation without regulation. |
| Gain-Bandwidth Product | 8 MHz - enables stable unity-gain buffer or closed-loop gain ≥2 configurations up to ~4 MHz. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - sufficient for 12-bit DAC output settling and fast pulse amplification. |
| Input Offset Voltage | 250 µV (max 2000 µV over −40°C to 125°C) - ensures ≤0.5 LSB error when driving 12-bit ADCs with 2.048 V reference. |
| Supply Current per Channel | 650 µA - allows integration of multiple channels in power-budgeted IoT edge nodes. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves dynamic range in audio preamps and precision sensor signal chains. |
| Shutdown Current | 900 nA per channel - reduces system standby power by >99% versus active mode. |

Pinout & Package
TLV2780AIDR is supplied in the SOIC-8 (D) package (5.3 mm × 6.2 mm, 1.75 mm height), with industry-standard pin spacing (1.27 mm). The device includes shutdown control and is pin-compatible with other TLV278x family members in the same footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Rail-to-rail output capable of sourcing/sinking ±10 mA; drives 2 kΩ loads to within 180 mV of rails at 1.8 V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2780AIDR's 8 µV/°C; higher 350 µA supply current. | Better long-term stability in precision DC-coupled systems; less suitable for high-speed AC signal paths due to lower 350 kHz GBW. | Select OPA333AIDR when offset drift dominates error budget; choose TLV2780AIDR for bandwidth-sensitive, low-power AC applications. |
| TLV9001IDR | Higher 1 MHz GBW, lower 150 µA supply current, but only specified to 125°C with 3.3 V max supply - no 1.8 V operation. | Optimized for ultra-low-power always-on monitoring; lacks rail-to-rail input capability below 2.7 V. | Choose TLV9001IDR for sub-150 µA systems with 3.3 V supply; retain TLV2780AIDR for true 1.8 V compatibility and rail-to-rail input at low voltage. |
Compared with OPA333AIDR and TLV9001IDR, TLV2780AIDR uniquely balances 8 MHz bandwidth, 1.8 V operation, rail-to-rail I/O, and industrial temperature range - making it the only choice for high-fidelity, low-voltage signal chains where both speed and supply flexibility are mandatory.

FAQ
What is the maximum operating supply voltage for TLV2780AIDR?
The absolute maximum supply voltage for TLV2780AIDR 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. At 3.6 V, TLV2780AIDR delivers optimal slew rate (5 V/µs) and output drive capability while maintaining rail-to-rail functionality - critical for high-dynamic-range signal paths.
Does TLV2780AIDR support rail-to-rail input at 1.8 V supply?
Yes, TLV2780AIDR supports rail-to-rail input with a common-mode range of −0.2 V to VDD+0.2 V across its full 1.8 V to 3.6 V supply range. At 1.8 V, this means inputs can be accepted from −0.2 V to +2.0 V - enabling direct interfacing with signals referenced to negative supplies or external references without level-shifting circuitry. This feature is explicitly validated in the datasheet's VICR specification table.
What is the typical shutdown current of TLV2780AIDR?
The typical shutdown current of TLV2780AIDR is 900 nA per channel at 25°C, with a maximum of 1700 nA over the full −40°C to 125°C temperature range. When the SHDN pin is pulled low, the amplifier disables and outputs enter high-impedance state. This ultra-low shutdown current makes TLV2780AIDR ideal for battery-operated devices requiring aggressive power cycling, such as wireless sensor nodes with multi-day sleep intervals.
Can TLV2780AIDR drive a 1000 pF capacitive load directly?
No, TLV2780AIDR is not stable driving >10 pF capacitive loads directly. The datasheet recommends adding a series null resistor (RNULL) between the output and load for CL > 10 pF to preserve phase margin and prevent oscillation. At 1000 pF, RNULL ≈ 20 Ω to 50 Ω is typically required depending on gain configuration. This limitation arises from internal compensation optimized for resistive loads and must be addressed in layout to ensure reliable operation.
What is the input offset voltage specification for TLV2780AIDR over temperature?
TLV2780AIDR has a maximum input offset voltage of 2000 µV over the full −40°C to 125°C industrial temperature range, with a typical value of 250 µV at 25°C. Its offset voltage drift is specified at 8 µV/°C, meaning worst-case drift contributes ≤1320 µV across the full range. This performance is confirmed in the "electrical characteristics" table under TLV278xA grade, making TLV2780AIDR suitable for applications requiring consistent DC accuracy without calibration.
