Product details
Overview
TLV2783CDGSRG4 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, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate, and 9 nV/√Hz input voltage noise at 10 kHz - enabling high-resolution data acquisition in battery-powered sensor front-ends and portable medical devices.
For engineers reviewing the TLV2783CDGSRG4 datasheet, TLV2783CDGSRG4 pinout, TLV2783CDGSRG4 application, or TLV2783CDGSRG4 equivalent, key selection criteria include its 650 µA/channel supply current, −40°C to 125°C industrial temperature range (C-suffix), shutdown capability, and MSOP-10 package compatibility with space-constrained analog signal chains.
Technical Context
The TLV2783CDGSRG4 implements a CMOS input stage with rail-to-rail input common-mode range extending to −0.2 V below ground and +0.2 V above VDD, supporting single-supply operation down to 1.8 V. Its internal architecture enables stable unity-gain operation with 58° phase margin into 2 kΩ//25 pF loads.
It integrates independent shutdown control per channel (pins 5 and 12), reducing supply current to ≤1.7 µA total when both channels are disabled. The device maintains rail-to-rail output swing across full temperature and supply ranges, with VOH ≥ 2.6 V and VOL ≤ 170 mV at VDD = 2.7 V and IOL = 5 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports direct operation from two alkaline or rechargeable cells without regulation. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop gain up to 10× at 800 kHz for anti-aliasing filter drivers. |
| Slew Rate | 4.8 V/µs (positive), 2.8 V/µs (negative) at VDD = 2.7 V - supports 12-bit DAC output settling within 2.4 µs at 0.01% accuracy. |
| Input Voltage Noise | 9 nV/√Hz at 10 kHz - preserves SNR in audio preamps and precision instrumentation amplifiers. |
| Supply Current per Channel | 650 µA typical - allows dual-channel operation under 1.3 mA, critical for multi-sensor IoT nodes. |
| Input Offset Voltage | 3000 µV max (C-grade, 0°C to 70°C) - enables DC-coupled transducer interfaces with <0.1% gain error at unity gain. |
| Shutdown Current | ≤1.7 µA total (both channels) - extends battery life in duty-cycled sensor readout systems. |
| Operating Temperature | 0°C to 70°C (C-suffix) - qualified for commercial-grade embedded control and consumer electronics. |
Pinout & Package
TLV2783CDGSRG4 is housed in a 10-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. 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 (OUT A) | Channel A output | Rail-to-rail sourcing/sinking up to ±10 mA; high-impedance during shutdown. |
| 2 (IN− A) | Channel A inverting input | CMOS input with 2.5 pA bias current; sensitive to layout-induced leakage. |
| 3 (IN+ A) | Channel A noninverting input | Supports common-mode voltages from −0.2 V to VDD+0.2 V. |
| 4 (GND) | Analog ground reference | Must connect to low-impedance ground plane; separate from digital ground if mixed-signal PCB. |
| 5 (SHDN A) | Channel A shutdown control | Logic-low (≤0.6 V) disables channel A; floating or logic-high (≥2 V) enables. |
| 6 (VDD) | Positive supply rail | Accepts 1.8–3.6 V; requires local 0.1 µF ceramic decoupling within 0.1 inch. |
| 7 (OUT B) | Channel B output | Independent rail-to-rail output; electrically isolated from OUT A. |
| 8 (IN− B) | Channel B inverting input | Matched to IN− A for dual-channel differential sensing applications. |
| 9 (IN+ B) | Channel B noninverting input | Enables dual-channel instrumentation amplifier configurations with shared reference. |
| 10 (SHDN B) | Channel B shutdown control | Independent control allows asymmetric power management between channels. |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| TLV2783IDGSR | Same silicon, −40°C to 125°C industrial temperature grade; 2000 µV max VIO at 25°C. | Required for automotive cabin modules or outdoor industrial enclosures exceeding 70°C ambient. | Select TLV2783IDGSR when extended temperature qualification and tighter offset are mandatory. |
| OPA2333AIDGSR | Zero-drift architecture; 0.02 µV/°C drift vs. TLV2783CDGSRG4's 8 µV/°C; higher 350 µA/channel current. | Better for DC-coupled thermocouple amplifiers where long-term offset stability dominates over speed. | Choose OPA2333AIDGSR only when microvolt-level DC accuracy outweighs 8 MHz bandwidth and 650 µA power budget. |
Compared with TLV2783CDGSRG4, TLV2783IDGSR offers wider temperature coverage and lower initial offset but same speed/power; OPA2333AIDGSR trades bandwidth and quiescent current for near-zero drift - making TLV2783CDGSRG4 optimal for cost-sensitive, battery-powered AC-coupled signal chains requiring speed and efficiency.

FAQ
What is the maximum recommended supply voltage for TLV2783CDGSRG4?
The absolute maximum supply voltage for TLV2783CDGSRG4 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 shift or reliability degradation, especially at elevated temperatures. Operation at 3.6 V enables full rail-to-rail output swing while maintaining 650 µA/channel supply current.
Does TLV2783CDGSRG4 support true rail-to-rail input common-mode range?
Yes, TLV2783CDGSRG4 supports a verified input common-mode voltage range of −0.2 V to VDD+0.2 V across its full operating temperature and supply range. This allows direct interfacing with ground-referenced sensors and signals that swing below GND or above VDD - a key enabler for single-supply 1.8 V systems where traditional op-amps would saturate.
How does the shutdown function operate on TLV2783CDGSRG4?
TLV2783CDGSRG4 features independent shutdown pins (pin 5 for channel A, pin 10 for channel B). Driving either pin to ≤0.6 V disables the corresponding amplifier, reducing its supply current to ≤1.7 µA total for both channels. The output enters high-impedance state. Pins may be left floating or pulled high (≥2 V) to enable - but floating requires careful layout to avoid parasitic turn-off.
What is the typical input offset voltage specification for TLV2783CDGSRG4?
The TLV2783CDGSRG4 has a maximum input offset voltage of 3000 µV over the 0°C to 70°C commercial temperature range, with a typical value of 250 µV at 25°C. Its temperature coefficient is 8 µV/°C, meaning offset drift remains predictable and bounded - critical for DC-coupled applications like strain gauge amplifiers where calibration intervals exceed 6 months.
Can TLV2783CDGSRG4 drive capacitive loads directly without external compensation?
TLV2783CDGSRG4 maintains ≥58° phase margin into 25 pF loads with 2 kΩ series resistance, allowing direct connection to typical 10–20 pF ADC input capacitors. For loads >25 pF, a small series resistor (e.g., 10–50 Ω) is recommended at the output to preserve stability - per Figure 30 in the SLOS245E datasheet. No internal compensation network is required.
