Texas Instruments TLV2784AIDR

Overview

TLV2784AIDR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power precision signal conditioning. 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, −40°C to 125°C industrial temperature range, and consumes only 650 µA per channel - enabling high-resolution data acquisition in battery-powered sensor front-ends and portable medical devices.

For engineers reviewing the TLV2784AIDR datasheet, TLV2784AIDR pinout, TLV2784AIDR application, or TLV2784AIDR equivalent, this page provides verified electrical specifications, TSSOP-14 package terminal mapping, rail-to-rail I/O behavior at sub-2-V operation, shutdown functionality timing, and validated alternatives for low-noise analog signal chains requiring <9 nV/√Hz noise at 10 kHz.

Technical Context

The TLV2784AIDR implements a CMOS input stage with rail-to-rail common-mode input voltage range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing, supporting single-supply operation down to 1.8 V while maintaining 8 MHz bandwidth. Its internal architecture enables stable unity-gain operation with 58° phase margin into 2 kΩ//25 pF loads.

Each of the four amplifiers features independent shutdown control (pins 5 and 13), reducing supply current to ≤1.7 µA per channel when disabled. Input bias current is 2.5 pA typical, input offset voltage is 250 µV max at 25°C (3000 µV over full temperature range), and THD+N is 0.055% at AV = 1, making it suitable for driving SAR ADCs and precision transimpedance stages.

FAQ

What is the maximum recommended supply voltage for TLV2784AIDR?

The absolute maximum supply voltage for TLV2784AIDR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V risks parametric degradation and reduced long-term reliability. At 3.6 V, the device achieves its highest slew rate (5 V/µs) and output drive capability while remaining within safe thermal limits for the TSSOP-14 package.

Does TLV2784AIDR support true rail-to-rail input common-mode range?

Yes, TLV2784AIDR supports a common-mode input voltage range from −0.2 V to VDD+0.2 V, exceeding the supply rails. This allows direct interfacing with signals that swing slightly beyond GND or VDD - such as DAC outputs with overshoot or sensor signals referenced to split supplies - without external clamping or level-shifting circuitry.

How does the shutdown function operate on TLV2784AIDR?

TLV2784AIDR has two independent shutdown pins: Pin 5 controls Amplifiers 1 and 2; Pin 13 controls Amplifiers 3 and 4. Driving either pin below 0.6 V disables the associated pair, reducing supply current to ≤1.7 µA per channel. Turn-on time is 800 ns; turn-off time is 200 ns. The outputs enter high-impedance state during shutdown, preventing loading of downstream circuitry.

Can TLV2784AIDR drive capacitive loads without instability?

TLV2784AIDR is stable for capacitive loads ≤10 pF with unity-gain configuration. For larger loads (e.g., ADC input capacitance or long PCB traces), a series resistor (RNULL) of 10–50 Ω should be placed between the op-amp output and the load to restore phase margin. Figure 30 in the SLOS245E datasheet confirms this snubber technique maintains ≥58° phase margin even with 100 pF loads.

What is the input offset voltage specification for TLV2784AIDR over temperature?

TLV2784AIDR has a maximum input offset voltage of 2000 µV over the full −40°C to +125°C range, with a typical value of 250 µV at 25°C. Its temperature coefficient is 8 µV/°C, meaning offset drift contributes ≤1.2 mV over the full range - acceptable for 12-bit systems with ≥2.5 V reference but may require calibration in 16-bit precision applications.
