Product details
Overview
TLV2783IDR 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 at 2.7 V, and 9 nV/√Hz input voltage noise at 10 kHz - enabling high-resolution data acquisition in battery-powered instrumentation and portable medical sensors.
For engineers reviewing the TLV2783IDR datasheet, TLV2783IDR pinout, TLV2783IDR application, or TLV2783IDR equivalent, this page provides verified package mapping (DGS-10), confirmed shutdown functionality, validated industrial-grade (−40°C to 125°C) performance, and real-world design implications of its rail-to-rail I/O, ultralow supply current (650 µA/channel), and 0.2 V beyond-rail common-mode input range.
Technical Context
The TLV2783IDR implements a CMOS input stage with complementary differential pairs enabling rail-to-rail input operation down to −0.2 V and up to VDD + 0.2 V. Its output stage uses a push-pull configuration delivering true rail-to-rail swing with <240 mV low-level output voltage at 5 mA sink current under 1.8 V supply.
It integrates an active shutdown control (SHDN pin) that reduces supply current to ≤1.7 µA/channel while placing outputs in high-impedance state - critical for power-gated sensor front-ends. The device maintains stable unity-gain operation with ≥58° phase margin into 25 pF capacitive loads at 1.8 V–2.7 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports single-cell Li-ion (3.0–3.6 V) and two-cell NiMH (2.4 V) systems without level-shifting. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop operation up to ~1 MHz with gain ≥8 in transimpedance or filter applications. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - supports 12-bit DAC settling in <1.7 µs for 0.01% accuracy with 1 VPP step. |
| Input Voltage Noise | 9 nV/√Hz at 10 kHz - preserves SNR in audio preamps and sensor amplifiers with bandwidths up to 20 kHz. |
| Supply Current per Channel | 650 µA - draws only 1.3 mA total for dual-channel operation, extending battery life in portable ECG monitors. |
| Common-Mode Input Range | −0.2 V to VDD + 0.2 V - accepts ground-referenced signals and allows direct interfacing with ADCs operating at same supply. |
| Shutdown Current | ≤1.7 µA per channel - reduces system standby power by >99% versus active mode in intermittent-sampling architectures. |
Pinout & Package
TLV2783IDR is packaged in a 10-pin DGS (MSOP PowerPAD™) thermally enhanced MSOP variant with exposed thermal pad. Pin 1 is marked via dot; pin numbering follows standard MSOP convention (counterclockwise from dot).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±10 mA; high-impedance during shutdown. |
| 2 (IN− A) | Channel A inverting input | High-impedance CMOS node; requires short trace routing to minimize parasitic capacitance and oscillation risk. |
| 3 (IN+ A) | Channel A noninverting input | Accepts signals from −0.2 V to VDD + 0.2 V; enables single-supply sensor biasing without external level shift. |
| 4 (GND) | Analog ground reference | Must connect directly to low-impedance ground plane; shared with thermal pad for optimal thermal dissipation. |
| 5 (SHDN A) | Channel A shutdown control | Active-low logic input; <0.6 V disables amp, >2 V enables; floating state defaults to enabled but risks leakage-induced shutdown. |
| 6 (VDD) | Positive supply rail | Accepts 1.8–3.6 V; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling per TI layout guidelines. |
| 7 (SHDN B) | Channel B shutdown control | Independent control per channel; allows asymmetric power gating in multi-stage signal chains. |
| 8 (IN+ B) | Channel B noninverting input | Electrically identical to Pin 3; supports differential pair configurations or independent signal paths. |
| 9 (IN− B) | Channel B inverting input | Matches Pin 2 characteristics; layout symmetry recommended to minimize inter-channel crosstalk (<−120 dB @ 100 kHz). |
| 10 (OUT B) | Channel B output | Functionally identical to Pin 1; outputs remain isolated during shutdown of opposite channel. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2783IDGKR | Same die, MSOP-8 package (DGK) - lacks dedicated SHDN pins for each channel; shares single shutdown control. | Not suitable for per-channel power gating; requires external logic for independent channel disable. | Select TLV2783IDR when independent shutdown of dual channels is required for adaptive power management. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2783IDR's 8 µV/°C; higher 350 µA/channel supply current. | Better DC precision for long-term sensor calibration; less suitable for high-speed AC-coupled signal paths due to 350 kHz GBW. | Select OPA2333AIDR when sub-µV offset stability over temperature dominates over bandwidth and power. |
Compared with TLV2783IDR, TLV2783IDGKR sacrifices per-channel shutdown control for smaller footprint, while OPA2333AIDR trades bandwidth and power efficiency for ultra-low drift - making TLV2783IDR optimal for cost-sensitive, battery-constrained, wideband analog front-ends requiring independent channel management.

FAQ
What is the maximum capacitive load the TLV2783IDR can drive without external compensation?
The TLV2783IDR maintains ≥58° phase margin with up to 25 pF capacitive load at unity gain when supplied at 1.8 V–2.7 V. For loads >10 pF, TI recommends adding a 10–50 Ω series null resistor (RNULL) between output and load to suppress ringing - verified in Figure 30 of the SLOS245E datasheet. Driving >100 pF directly risks instability and overshoot in pulse response.
Does the TLV2783IDR support true rail-to-rail input when powered from 1.8 V?
Yes. The TLV2783IDR guarantees common-mode input range from −0.2 V to VDD + 0.2 V across its full operating temperature range. At 1.8 V supply, this means inputs function correctly from −0.2 V to 2.0 V - enabling direct interface with 0 V–1.8 V sensors and eliminating need for external bias networks in single-supply designs using TLV2783IDR.
How does the shutdown feature affect output state in the TLV2783IDR?
When either SHDN A or SHDN B pin is pulled low (<0.6 V), the corresponding amplifier channel enters shutdown mode: supply current drops to ≤1.7 µA, and its output transitions to high-impedance (Hi-Z) state - not tri-state or forced rail. This prevents loading of downstream circuits during sleep. Both channels operate independently, allowing one channel to remain active while the other is disabled in TLV2783IDR.
What is the typical input offset voltage specification for the TLV2783IDR over temperature?
The TLV2783IDR has a maximum input offset voltage of 3000 µV over the full −40°C to 125°C industrial temperature range, with typical value of 250 µV at 25°C. Its temperature coefficient is 8 µV/°C - meaning offset drift contributes ≤1.2 mV additional error across a 150°C span. This is documented in Table 1 (dc performance) of the SLOS245E datasheet for TLV278xI grade parts like TLV2783IDR.
Can the TLV2783IDR be used in inverting amplifier configurations with gain >10 without stability issues?
Yes. The TLV2783IDR achieves ≥58° phase margin at unity gain into 25 pF, and its gain-bandwidth product remains stable at 8 MHz across supply voltages (1.8–3.6 V). For inverting configurations with gain = 10, the closed-loop bandwidth is ~800 kHz - well within stable region. Layout best practices (short traces, local decoupling, ground plane under thermal pad) are essential to maintain this stability, as confirmed in TI's Application Information section (SLOS245E, pp. 13–15).
