Texas Instruments TLV2783ID

Overview

TLV2783ID 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 bandwidth and 4.8 V/µs slew rate at just 650 µA per channel, and supports −40°C to 125°C industrial temperature range. It is used in high-resolution data converter front-ends and portable sensor signal conditioning.

For engineers reviewing the TLV2783ID datasheet, TLV2783ID pinout, TLV2783ID application, or TLV2783ID equivalent, key selection criteria include its rail-to-rail I/O swing at 1.8 V, shutdown capability (900 nA/channel), low 9 nV/√Hz input noise at 10 kHz, and MSOP-8 package compatibility with space-constrained industrial sensing and battery-powered instrumentation designs.

Technical Context

The TLV2783ID implements a CMOS input stage enabling rail-to-rail common-mode input voltage range (−0.2 V to VDD+0.2 V) and ultra-low input bias current (2.5 pA typical). 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), placing outputs in high-impedance state and reducing supply current to ≤1.7 µA total when active channels are disabled. The device maintains specified performance across full industrial temperature range without derating of bandwidth or slew rate.

Key Specifications

Pinout & Package

TLV2783ID is housed in a 3.0 mm × 3.0 mm, 8-pin MSOP (DGK) package with exposed thermal pad (not electrically connected). Pin 1 is marked by a dot; pin numbering follows standard MSOP convention.

FAQ

What is the maximum capacitive load the TLV2783ID can drive without external compensation?

The TLV2783ID is stable for capacitive loads up to 10 pF with no series resistor. For loads >10 pF, TI recommends adding a 5–50 Ω null resistor (RNULL) in series with the output to maintain ≥58° phase margin and prevent ringing-verified in Figure 18 of the SLOS245E datasheet at 25°C with RL = 2 kΩ.

Does the TLV2783ID support true single-supply operation down to 1.8 V with rail-to-rail input and output?

Yes. The TLV2783ID supports rail-to-rail input common-mode range from −0.2 V to VDD+0.2 V and rail-to-rail output swing within 180 mV of each rail at 1 mA load (VDD = 1.8 V). This enables full-scale signal handling in 1.8 V systems without level-shifting circuitry-confirmed in Sections 6 and 7 of the SLOS245E datasheet.

How does the shutdown function behave on the TLV2783ID, and what is the leakage risk if SHDN pins are left floating?

Each amplifier in the TLV2783ID has an independent active-low shutdown pin (pin 5 for A, pin 12 for B). Pulling either pin <0.6 V disables that channel and reduces its supply current to ≤1.7 µA total. Floating SHDN pins default to enabled-but parasitic leakage >100 nA may falsely trigger shutdown; TI recommends pulling unused SHDN pins to VDD via ≤100 kΩ resistor.

What is the typical input bias current of the TLV2783ID, and why is it critical for high-impedance sensor interfaces?

The TLV2783ID features a CMOS input stage with typical input bias current of 2.5 pA (max 300 pA over −40°C to 125°C). This ultra-low value prevents significant voltage drop across high-impedance sources (e.g., pH electrodes or piezoelectric sensors), preserving signal fidelity and eliminating need for guard traces or bias-current compensation networks.

Can the TLV2783ID be used in unity-gain stable configurations, and what is its phase margin under typical conditions?

Yes, the TLV2783ID is unity-gain stable. At VDD = 2.7 V, RL = 2 kΩ, CL = 25 pF, and TA = 25°C, it achieves 58° phase margin (Figure 13, SLOS245E), ensuring robust stability in voltage-follower and gain-of-one configurations without external compensation components.
