Texas Instruments TLV2783IN

Overview

TLV2783IN from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It operates from 1.8 V to 3.6 V supply, 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 instrumentation and portable data acquisition systems.

For engineers reviewing the TLV2783IN datasheet, TLV2783IN pinout, TLV2783IN application, or TLV2783IN equivalent, this device is selected for precision analog front-ends requiring wide common-mode range (−0.2 V to VDD+0.2 V), low input noise (9 nV/√Hz at 10 kHz), and shutdown capability with 900 nA/channel quiescent current.

Technical Context

The TLV2783IN 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 within 180 mV of each rail at 1.8 V supply. Its internal architecture supports stable unity-gain operation with 58° phase margin into 2 kΩ//25 pF loads.

It integrates independent shutdown control per amplifier (pins 5 and 12), enabling dynamic power management in multi-channel systems. The device maintains specified performance across −40°C to +125°C industrial temperature range and exhibits 70 dB CMRR at 2.7–3.6 V supplies with 1.2 V to VDD common-mode input.

FAQ

What is the maximum supply voltage for TLV2783IN, and what happens if exceeded?

The absolute maximum supply voltage for TLV2783IN is 4 V. Exceeding this rating - even momentarily - risks permanent damage to the internal CMOS circuitry. Operation above 3.6 V violates recommended conditions and may cause increased input bias current, reduced phase margin, or latch-up. Always use overvoltage protection (e.g., Zener clamp or TVS diode) in systems with unstable power rails.

Does TLV2783IN support true rail-to-rail input when powered from 1.8 V?

Yes, TLV2783IN supports rail-to-rail input with common-mode range from −0.2 V to VDD+0.2 V. At 1.8 V supply, this means inputs can be as low as −0.2 V and as high as 2.0 V - fully encompassing the supply rails. This capability is confirmed across the full −40°C to +125°C temperature range and enables direct interfacing with sensors or DACs that swing beyond the supply.

How does the shutdown function behave on TLV2783IN, and what is the output state?

When SHDN A (pin 5) or SHDN B (pin 12) is pulled ≤0.6 V, the corresponding amplifier enters shutdown mode: supply current drops to 900 nA/channel, and its output goes into high-impedance state - neither sourcing nor sinking current. Outputs remain floating, so external pull-up/down resistors may be needed to define voltage during shutdown. Leaving SHDN pins unconnected enables the amplifiers by default.

Can TLV2783IN drive a 10-kΩ load while maintaining rail-to-rail output swing at 1.8 V?

Yes, TLV2783IN maintains rail-to-rail output swing into 10-kΩ loads at 1.8 V supply. Typical high-level output voltage is 1.77 V (VOH) and low-level is 155 mV (VOL) at 1 mA load - meaning it swings within 230 mV of VDD and 155 mV of GND. For heavier loads (e.g., 2 kΩ), output swing degrades slightly but remains functional for most precision applications.

What is the typical input offset voltage drift over temperature for TLV2783IN?

The temperature coefficient of input offset voltage (αVIO) for TLV2783IN is 8 µV/°C. Over a −40°C to +125°C range (165°C span), this results in a worst-case drift of ±1.32 mV added to the initial offset. Combined with a max 4500 µV initial offset, total input-referred error stays within ±5.82 mV - sufficient for 12-bit systems but may require calibration in 14+ bit applications.
