Product details
Overview
TLV2783IDGSR from Texas Instruments is a dual 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, and 9 nV/√Hz input noise at 10 kHz - enabling high-resolution data acquisition in battery-powered sensor front-ends and portable instrumentation.
For engineers reviewing the TLV2783IDGSR datasheet, TLV2783IDGSR pinout, TLV2783IDGSR application, or TLV2783IDGSR equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, shutdown capability (900 nA/channel), MSOP-10 package footprint, and verified rail-to-rail I/O performance across full supply range.
Technical Context
The TLV2783IDGSR 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. 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 without external compensation.
Each channel features independent shutdown control (SHDN pin), enabling dynamic power management in multi-amplifier systems. The device maintains 650 µA per-channel quiescent current across 1.8–3.6 V supply and exhibits 70 dB CMRR at 1.2 V to VDD input range - critical for rejecting supply and reference noise in single-supply ADC driver stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports two-cell Li-ion or NiMH battery operation without regulation. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop gain up to 10× at 800 kHz for anti-aliasing filter interfaces. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - supports 12-bit DAC settling in <2.4 µs with 0.01% accuracy. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in precision sensor amplification before 16-bit ADCs. |
| Input Offset Voltage | 3000 µV max (I-grade) - ensures ≤0.3 mV error in 1 V full-scale 12-bit measurement systems. |
| Shutdown Current | 900 nA per channel - extends battery life >100× vs active mode in intermittent-sampling applications. |
| Operating Temperature | −40°C to 125°C - qualified for automotive cabin sensors and industrial motor control feedback loops. |
Pinout & Package
TLV2783IDGSR is housed in a 10-pin MSOP (DGK) package with 0.5 mm pitch, 3.0 mm × 3.0 mm body, and exposed thermal pad. Pin 1 is marked by a dot; pin numbering follows standard MSOP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Delivers rail-to-rail swing; drives 2 kΩ loads with <290 mV VOL at 5 mA sink. |
| 2 (IN−1) | Channel 1 inverting input | High-impedance CMOS node; requires short trace routing to minimize stray capacitance. |
| 3 (IN+1) | Channel 1 noninverting input | Accepts signals from −0.2 V to VDD+0.2 V; enables true single-supply sensor biasing. |
| 4 (GND) | Analog ground reference | Shared return path for both channels; must connect to low-impedance ground plane. |
| 5 (SHDN1) | Channel 1 shutdown control | Active-low logic input; pulls to GND to disable channel and reduce IDD to 900 nA. |
| 6 (VDD) | Positive supply rail | Accepts 1.8–3.6 V; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling. |
| 7 (OUT2) | Channel 2 output | Independent rail-to-rail output; electrically isolated from OUT1 except via shared VDD/GND. |
| 8 (IN−2) | Channel 2 inverting input | Matched to IN−1; supports differential pair configurations with <3000 µV input offset mismatch. |
| 9 (IN+2) | Channel 2 noninverting input | Identical VICR spec as IN+1; enables dual-channel synchronous sampling front-ends. |
| 10 (SHDN2) | Channel 2 shutdown control | Independent enable/disable; allows asymmetric power gating in multi-stage signal chains. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8 V systems - e.g., 0–1.8 V output swing driving SAR ADC references. |

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 |
|---|---|---|---|
| TLV2783IDR | Same die, SOIC-8 package (D), no shutdown pins, fixed dual-channel configuration. | Lacks per-channel shutdown; unsuitable for dynamic power-gated designs but offers lower cost and larger solder pads. | Select TLV2783IDR only when board space allows SOIC-8 and shutdown functionality is unnecessary. |
| OPA2333AIDGSR | Zero-drift architecture, 0.02 µV/°C drift, 60 µA/channel, 350 kHz GBW - trades speed for ultra-low offset stability. | Better for DC-critical applications (e.g., weigh scales); insufficient bandwidth for >10 kHz sensor signals. | Choose OPA2333AIDGSR when long-term offset drift <1 µV matters more than 8 MHz bandwidth. |
Compared with TLV2783IDR, TLV2783IDGSR provides per-channel shutdown in a smaller MSOP-10 footprint but requires additional PCB routing for SHDN lines; versus OPA2333AIDGSR, it delivers 23× higher bandwidth at the cost of 10× higher input offset drift - making it optimal for AC-coupled, medium-speed precision sensing.

FAQ
What is the maximum recommended supply voltage for TLV2783IDGSR?
The absolute maximum supply voltage for TLV2783IDGSR 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 high temperature. At 3.6 V, the device achieves optimal slew rate (5 V/µs) and output drive capability while remaining within safe power dissipation limits for the MSOP-10 package.
Does TLV2783IDGSR support true rail-to-rail input common-mode range?
Yes, TLV2783IDGSR supports a common-mode input voltage range from −0.2 V to VDD+0.2 V, which exceeds the supply rails. This allows direct interface to grounded sensors or bipolar signal sources in single-supply systems without level-shifting circuitry. The specification is verified across the full −40°C to 125°C temperature range and holds for both input terminals simultaneously.
How does the shutdown feature operate on TLV2783IDGSR?
TLV2783IDGSR has two independent active-low shutdown pins (pins 5 and 10). Pulling either SHDN pin to GND disables its respective amplifier channel, reducing supply current to 900 nA per disabled channel and placing the output in high-impedance state. Leaving SHDN floating or tying it to VDD enables normal operation. The turn-on/turn-off times are 800 ns and 200 ns respectively, enabling rapid power cycling in burst-mode sensing applications.
Can TLV2783IDGSR drive capacitive loads without oscillation?
TLV2783IDGSR is stable for capacitive loads ≤10 pF with no series resistance. For loads >10 pF, a series resistor (RNULL) of 10–50 Ω must be placed between the output and load to maintain ≥58° phase margin and prevent ringing. This requirement is confirmed in Figure 18 of the datasheet and applies across all supply voltages and temperatures - critical for driving ADC input capacitors or long PCB traces.
What is the input bias current specification for TLV2783IDGSR?
The input bias current for TLV2783IDGSR is 2.5 pA typical and 300 pA maximum across the full −40°C to 125°C industrial temperature range. This ultra-low value results from its CMOS input stage and enables high-impedance sensor interfacing - such as pH electrodes (>10⁹ Ω source impedance) or photodiode transimpedance amplifiers - without significant offset error or signal attenuation.
