Product details
Overview
TLV2783AID 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 noise at 10 kHz - enabling high-resolution data acquisition in battery-powered sensor front-ends and portable instrumentation.
For engineers reviewing the TLV2783AID datasheet, TLV2783AID pinout, TLV2783AID application, or TLV2783AID equivalent, this page provides verified circuit role, industrial-grade (−40°C to 125°C) temperature performance, shutdown functionality, MSOP-8 package mapping, and real-world design implications for low-noise, low-supply analog signal chains.
Technical Context
The TLV2783AID implements a CMOS input stage with rail-to-rail input common-mode range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing, supporting single-supply operation down to 1.8 V while maintaining 8 MHz bandwidth and 650 µA/channel supply current. 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 (SHDN pins), reducing supply current to ≤1.7 µA per channel in disabled state. Input bias current is 2.5 pA typical, and input offset voltage is trimmed to 250 µV max at 25°C (3000 µV over −40°C to 125°C), making it suitable for high-impedance transducer interfaces requiring minimal DC error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports single-cell Li-ion or two NiMH batteries without regulation. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop operation up to ~1 MHz with gain ≥8 in unity-gain-compensated configuration. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - supports 1-Vpp signals up to ~760 kHz full-power bandwidth. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in audio and sensor signal amplification stages. |
| Input Offset Voltage | 250 µV max at 25°C (3000 µV over −40°C to 125°C) - ensures <0.1% gain error in 12-bit ADC driver applications. |
| Supply Current per Channel | 650 µA typical - enables dual-channel operation at <1.3 mA total, critical for always-on sensing nodes. |
| Shutdown Current | ≤1.7 µA per channel - reduces system standby power by >99% when channels are inactive. |
Pinout & Package
TLV2783AID is housed in a 3.0 mm × 3.0 mm, 0.65 mm pitch MSOP-8 (DGK) package with exposed thermal pad (not electrically connected). 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 voltage swing; capable of sourcing/sinking ±10 mA. |
| 2 (IN−1) | Channel 1 inverting input | High-impedance CMOS node; sensitive to layout-induced parasitic capacitance. |
| 3 (IN+1) | Channel 1 noninverting input | Accepts common-mode voltages from −0.2 V to VDD+0.2 V - extends dynamic range beyond rails. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must connect directly to low-impedance ground plane. |
| 5 (SHDN1) | Channel 1 shutdown control | Active-low logic input; ≤0.6 V disables channel, ≥2 V enables; floating = enabled. |
| 6 (VDD) | Positive supply | 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; no crosstalk with OUT1 in shutdown mode (≥120 dB isolation). |
| 8 (SHDN2) | Channel 2 shutdown control | Independent enable/disable control; allows asymmetric power management per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 1.8 V supply headroom - maximizes dynamic range in low-voltage ADC drivers. |
| 8 MHz GBW at 650 µA | Delivers high-speed precision without compromising battery life - 12× higher bandwidth per µA than legacy micropower op amps. |
| 2.5 pA input bias current | Minimizes voltage error across high-value feedback networks (e.g., 10 MΩ gain-setting resistors). |
| Independent per-channel shutdown | Allows selective channel disable in multi-stage filters or multiplexed sensor systems - eliminates need for external switches. |
| −40°C to 125°C operation | Qualified for under-hood automotive, industrial PLC, and outdoor IoT sensor nodes without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2783ID | Same MSOP-8 package and electrical specs, but 3000 µV max input offset (vs. 2000 µV for TLV2783AID) over −40°C to 125°C. | Acceptable for cost-sensitive industrial controls where <0.1% gain error is not required. | Select TLV2783ID if offset drift tolerance >3000 µV is acceptable and BOM cost reduction is prioritized. |
| OPA2333AIDRGT | Zero-drift architecture; 0.02 µV/°C offset drift vs. 8 µV/°C for TLV2783AID; higher 350 µA/channel supply current. | Better for DC-critical applications like precision weigh scales; less suitable for high-frequency sensor excitation. | Choose OPA2333AIDRGT only when sub-µV offset stability over temperature is mandatory and 8 MHz bandwidth is excessive. |
Compared with TLV2783ID, TLV2783AID offers tighter initial offset for improved factory calibration yield; compared with OPA2333AIDRGT, it delivers 23× lower supply current at 8× higher bandwidth - making it optimal for battery-powered, wideband analog signal chains where zero-drift isn't required.

FAQ
What is the maximum recommended supply voltage for TLV2783AID?
The absolute maximum supply voltage for TLV2783AID 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; operation at 3.6 V is fully characterized and supported across −40°C to 125°C.
Does TLV2783AID support true rail-to-rail input common-mode range?
Yes - TLV2783AID accepts input voltages from −0.2 V to VDD+0.2 V, meaning it operates with inputs extending 200 mV beyond both supply rails. This enables direct interfacing with sensors or DACs that swing below ground or above VDD, such as piezoelectric elements or level-shifted digital logic.
How does the shutdown function behave on TLV2783AID?
Each channel of TLV2783AID has an independent active-low shutdown pin (SHDN1/SHDN2). Pulling either pin ≤0.6 V disables its respective amplifier, reducing supply current to ≤1.7 µA and placing the output in high-impedance state. Leaving the pin floating or pulling ≥2 V enables normal operation.
Can TLV2783AID drive capacitive loads without external compensation?
TLV2783AID is stable for capacitive loads ≤10 pF with direct connection. For larger loads (e.g., ADC input capacitance >10 pF), a series resistor (RNULL) of 10–50 Ω must be added between the output and load to maintain ≥58° phase margin and prevent ringing - as confirmed in Figure 30 of the SLOS245E datasheet.
What is the guaranteed input offset voltage specification for TLV2783AID over temperature?
TLV2783AID guarantees ≤3000 µV input offset voltage across the full −40°C to 125°C operating range. At 25°C, the limit is tighter: ≤2000 µV. This A-grade binning enables higher accuracy in uncalibrated systems compared to standard TLV2783ID (3000 µV max over same range).
