Texas Instruments TLV2783CDR

Overview

TLV2783CDR 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, 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 TLV2783CDR datasheet, TLV2783CDR pinout, TLV2783CDR application, or TLV2783CDR equivalent, key selection criteria include its rail-to-rail I/O swing down to 1.8 V supply, −40°C to 125°C industrial temperature range (C-suffix variant is 0°C to 70°C), shutdown capability with 900 nA quiescent current, and MSOP-10 package compatibility with space-constrained PCB layouts.

Technical Context

The TLV2783CDR integrates two independent amplifiers with complementary input stages enabling rail-to-rail common-mode input voltage range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing. Its 8 MHz unity-gain bandwidth and 58° phase margin at 2 kΩ/25 pF load ensure stable operation in unity-gain follower and closed-loop configurations up to 100 kHz.

Each channel features an active shutdown terminal (SHDN) that disables the amplifier and places outputs in high-impedance state while reducing supply current to ≤1.7 µA over full temperature range. Input bias current is 2.5 pA typical, supporting high-impedance sensor interfaces without significant offset error.

FAQ

What is the maximum recommended supply voltage for TLV2783CDR?

The absolute maximum supply voltage for TLV2783CDR 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, especially at elevated temperatures. Operation at 3.6 V is valid and commonly used to maximize output swing in 3.3 V systems.

Does TLV2783CDR support true rail-to-rail input common-mode range?

Yes, TLV2783CDR supports a common-mode input voltage range from −0.2 V to VDD+0.2 V, which extends 0.2 V beyond both supply rails. This allows input signals to swing slightly below ground or above VDD - critical for interfacing with AC-coupled sensors or level-shifted logic without clamping diodes.

How does the shutdown function behave on TLV2783CDR pins 5 and 10?

Pins 5 and 10 are independent shutdown controls for Channels 1 and 2 respectively. Driving either pin below 0.6 V (VIL) disables its associated amplifier and places its output in high-impedance state. Supply current drops to ≤1.7 µA per channel. Leaving pins floating enables the channel, but parasitic leakage must be managed to avoid unintended shutdown.

Can TLV2783CDR drive a 10 kΩ load while maintaining rail-to-rail output swing?

Yes, TLV2783CDR maintains rail-to-rail output swing into 10 kΩ loads: at VDD = 1.8 V, VOH ≥ 1.77 V and VOL ≤ 180 mV with IO = ±1 mA; at VDD = 2.7 V, VOH ≥ 2.68 V and VOL ≤ 170 mV. Performance degrades only under heavier loads (>5 mA), where output swing compresses by ~100 mV.

What is the typical input bias current of TLV2783CDR and how does it affect high-impedance circuits?

The typical input bias current of TLV2783CDR is 2.5 pA at 25°C, with a maximum of 100 pA over the full 0°C to 70°C range. In a transimpedance amplifier with 1 GΩ feedback resistor, this introduces ≤100 µV of input-referred offset - negligible for most 12–14 bit precision applications but relevant for femtoampere-level photodiode sensing.
