Product details
Overview
TLV2783IDGS from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed signal conditioning in battery-powered systems. 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 precision amplification in portable medical sensors, industrial data loggers, and analog front-ends for 12-bit+ ADCs.
For engineers reviewing the TLV2783IDGS datasheet, TLV2783IDGS pinout, TLV2783IDGS application, or TLV2783IDGS equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, shutdown capability (900 nA/channel), rail-to-rail output swing down to 180 mV from rails at 1.8 V, and verified performance with capacitive loads up to 25 pF using RNULL compensation.
Technical Context
The TLV2783IDGS implements a CMOS input stage with 2.5 pA typical input bias current and 250 µV max input offset voltage (A-grade), supporting precision DC-coupled gain stages. Its unity-gain-stable architecture features 58° phase margin with 2 kΩ load and 25 pF capacitance, and maintains stable operation across supply voltages from 1.8 V to 3.6 V without external compensation.
It integrates independent shutdown control per channel (pins 5 and 12), enabling dynamic power management in multi-stage signal chains. The device's VICR extends to −0.2 V below ground and VDD+0.2 V, allowing true single-supply interfacing with bipolar input signals while preserving rail-to-rail output swing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - compatible with two alkaline or NiMH cells; eliminates need for LDO in ultra-low-power systems. |
| Gain-Bandwidth Product | 8 MHz - supports closed-loop gains up to 8× at 1 MHz or 1× at 8 MHz for anti-aliasing filter drivers. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - enables clean 1-VPP output at 1 MHz without slewing distortion. |
| Input Offset Voltage | 250 µV max (A-grade) - ensures ≤0.1% gain error in 100× instrumentation amplifier configurations. |
| Supply Current per Channel | 650 µA - allows dual-channel operation under 1.3 mA total, critical for 10-year battery life in IoT nodes. |
| Shutdown Current | 900 nA per channel - reduces system standby power by >99.9% versus active mode. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in audio preamps and sensor signal chains with bandwidth <100 kHz. |
| Common-Mode Input Range | −0.2 V to VDD+0.2 V - accepts inputs beyond rails for level-shifting and comparator-like interfacing. |
Pinout & Package
TLV2783IDGS is housed in a 10-pin MSOP (DGS) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. This thermally enhanced, surface-mount package supports high-density PCB layouts and improves power dissipation efficiency over SOIC variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Delivers rail-to-rail buffered signal; capable of sourcing/sinking ±10 mA into 2-kΩ load. |
| 2 | Channel 1 Inverting Input | High-impedance node (1000 GΩ); requires shortest possible trace to minimize noise pickup and parasitic capacitance. |
| 3 | Channel 1 Non-Inverting Input | Accepts common-mode voltages from −0.2 V to VDD+0.2 V; enables single-supply transducer interfacing. |
| 4 | Ground | Primary reference for all channels; must connect directly to solid ground plane with minimal via inductance. |
| 5 | Channel 1 Shutdown | Active-low control: <0.6 V disables amp (900 nA IDD), >2 V enables; floating = enabled. |
| 6 | VDD | Single positive supply input; requires local 0.1-µF ceramic + 6.8-µF tantalum decoupling per TI layout guidelines. |
| 7 | Channel 2 Output | Independent rail-to-rail output; electrically isolated from Channel 1 except shared VDD/GND. |
| 8 | Channel 2 Inverting Input | Matched to Pin 2; supports differential pair configurations with <100 µV inter-channel offset. |
| 9 | Channel 2 Non-Inverting Input | Matched to Pin 3; enables dual-sensor synchronous sampling with common-mode rejection. |
| 10 | Channel 2 Shutdown | Independent enable/disable control for Channel 2; allows asymmetric power sequencing in multi-stage filters. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input and Output | Enables full dynamic range utilization in 1.8-V systems - outputs swing within 180 mV of rails at 1.8 V, inputs accept signals 200 mV beyond supply rails. |
| Ultra-Low Supply Current | 650 µA per channel at 1.8 V–3.6 V allows dual op-amp integration in energy-harvesting nodes without compromising battery life. |
| Industrial Temperature Range | Specified from −40°C to +125°C ensures reliable operation in automotive engine compartments and factory-floor PLC modules. |
| Independent Per-Channel Shutdown | Two dedicated SHDN pins (Pins 5 & 10) permit selective channel disabling - e.g., disable buffer during ADC conversion to eliminate crosstalk. |
| Low Input Bias Current | 2.5 pA typical enables high-impedance sensor interfaces (e.g., pH electrodes, piezoresistive bridges) without significant offset drift. |
| Capacitive Load Drive Capability | Stable with 25-pF load (RL = 2 kΩ); supports direct connection to ADC input capacitors or long PCB traces without oscillation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2783IDGKR | Identical electrical specs and pinout; supplied in 250-piece mini-reel (T-suffix) or 3000-piece reel (R-suffix). | No functional difference; packaging variant only - suitable for automated SMT assembly but not hand-soldering prototyping. | Select TLV2783IDGKR for volume production; TLV2783IDGS remains optimal for engineering validation and low-volume builds. |
| OPA2333AIDGSR | Zero-drift architecture (0.02 µV/°C drift), lower VIO (10 µV max), higher supply current (17 µA/ch), no shutdown function. | Better DC precision for weigh-scale or strain-gauge applications; unsuitable where ultra-low power or shutdown is required. | Choose OPA2333AIDGSR only when sub-µV offset stability outweighs 26× higher quiescent current and loss of power gating. |
Compared with TLV2783IDGS, TLV2783IDGKR offers identical performance in tape-and-reel format for SMT lines, while OPA2333AIDGSR trades 26× higher supply current and no shutdown for zero-drift precision - making TLV2783IDGS the sole choice for battery-constrained, thermally variable, or dynamically powered systems.

FAQ
What is the maximum operating supply voltage for TLV2783IDGS?
The absolute maximum supply voltage for TLV2783IDGS 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 or permanent damage, especially at elevated temperatures. Operation at 3.6 V enables full rail-to-rail output swing and meets the 8-MHz bandwidth specification.
Does TLV2783IDGS support true rail-to-rail input common-mode range?
Yes, TLV2783IDGS supports a common-mode input voltage range (VICR) from −0.2 V to VDD+0.2 V. This means it accepts input signals 200 mV below ground and 200 mV above VDD, enabling direct interfacing with bipolar transducers or level-shifted signals in single-supply systems without external clamping diodes.
How does the shutdown function behave on TLV2783IDGS?
TLV2783IDGS features two independent active-low shutdown pins (Pins 5 and 10). Pulling either pin below 0.6 V disables its respective channel, reducing supply current to 900 nA per channel and placing the output in high-impedance state. Leaving the pin floating or pulling it above 2 V enables normal operation - no external pull-up is required.
Can TLV2783IDGS drive a 1000-pF capacitive load?
No, TLV2783IDGS is not stable with 1000-pF loads. The datasheet specifies stability up to 25 pF with 2-kΩ load; for larger capacitive loads, a series resistor (RNULL) must be added between the output and load. For 1000-pF, RNULL ≥ 100 Ω is typically required to maintain ≥45° phase margin and prevent ringing.
What is the thermal performance of the DGS package in TLV2783IDGS?
The TLV2783IDGS in the 10-pin MSOP (DGS) package has ΘJA = 257.7°C/W and ΘJC = 54.1°C/W. At 125°C ambient and 1.3 mA total supply current (2 × 650 µA), junction temperature rise is ~17.7°C - well within the 150°C absolute maximum. Use of the exposed thermal pad significantly improves heat dissipation versus non-thermal MSOP variants.
