Product details
Overview
OPA2836IDR from Texas Instruments is a dual-channel, ultra-low-power, rail-to-rail output, negative-rail input voltage-feedback operational amplifier. It delivers 205 MHz bandwidth, 560 V/µs slew rate, and 1 mA typical quiescent current per channel at 5 V supply, operating from –40°C to +125°C. It is used in portable SAR ADC drivers and low-power audio signal conditioning where high-speed performance and battery life are critical.
For engineers reviewing the OPA2836IDR datasheet, OPA2836IDR pinout, OPA2836IDR application, or OPA2836IDR equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases, and two validated alternative op-amps for low-power, high-bandwidth signal chain design.
Technical Context
The OPA2836IDR implements a voltage-feedback architecture with fully differential input stage enabling –0.2 V to +3.9 V input common-mode range (at 5 V supply) and rail-to-rail output swing. Its 205 MHz unity-gain bandwidth and 560 V/µs slew rate support fast settling (22 ns to 0.1%) and low distortion (–130 dBc THD at 1 kHz), making it suitable for driving high-resolution ADCs without gain error or harmonic corruption.
Each amplifier features independent power-down pins (PD1/PD2), reducing quiescent current to 0.5 µA per channel in shutdown mode. The device is characterized across –40°C to +125°C and supports single-supply operation from 2.5 V to 5.5 V, with PSRR of 108 dB and CMRR of 116 dB ensuring robustness against supply and common-mode noise.
Key Specifications

|---|---|
| Bandwidth | 205 MHz at G = 1 - enables accurate amplification of signals up to ~100 MHz before 3-dB roll-off |
| Slew Rate | 560 V/µs - supports clean 2-V step response in ≤3 ns without slewing-induced distortion |
| Quiescent Current | 1 mA per channel - allows dual-channel high-speed operation on coin-cell or Li-ion battery systems |
| Input Voltage Noise | 4.6 nV/√Hz at 100 kHz - preserves SNR in precision sensor front-ends and audio preamps |
| Settling Time (0.1%) | 22 ns for 2-V step - meets timing budgets for 16-bit+ SAR ADC sampling windows |

| 2 | VIN1− | Inverting input - accepts differential or single-ended feedback networks |
| 3 | VIN1+ | Noninverting input - supports wide common-mode range down to –0.2 V (5 V supply) |
| 4 | VS− | Negative supply pin - referenced to ground in single-supply configurations |
| 5 | VIN2+ | Amplifier 2 noninverting input - independent channel for dual-path signal processing |
| 6 | VIN2− | Amplifier 2 inverting input - electrically isolated from Channel 1 to minimize crosstalk (–120 dB) |
| 7 | VOUT2 | Amplifier 2 output - matched AC/DC performance to Channel 1 for synchronous acquisition |
| 8 | VS+ | Positive supply pin - operates from 2.5 V to 5.5 V; powers both amplifiers simultaneously |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 20 mV of supply rails at ±45 mA load - maximizes dynamic range into ADCs |
| Independent power-down control | PD1 and PD2 pins reduce each channel to 0.5 µA - enables selective channel shutdown in multi-stage chains |
| Negative-rail input capability | Accepts inputs down to –0.2 V (5 V supply) - simplifies level-shifting in bipolar-signal interfaces |
| Low THD and high SNR | –130 dBc THD and –117.6 dBc SNR at 1 kHz - preserves fidelity in audio and measurement front-ends |
| High CMRR and PSRR | 116 dB CMRR and 108 dB PSRR - rejects noise from shared supplies and noisy digital environments |
Applications
| Audio ADC Input Buffers | Low-Power SAR ADC Drivers |
|---|---|
Use Scenario: Buffering microphone or line-level analog signals before digitization in battery-powered voice recorders or smart speakers. IC Role / Device Role / Timing Role: Dual-channel OPA2836IDR serves as anti-aliasing filter driver and reference buffer with matched gain and phase response. Use Value: 205 MHz bandwidth ensures flat frequency response through audio band; 1 mA/channel quiescent current extends playback time by >30% vs legacy op-amps. |
Use Scenario: Driving the input of 16-bit/1 MSPS SAR ADCs in portable data loggers and handheld test equipment. IC Role / Device Role / Timing Role: Provides fast settling (22 ns to 0.1%) and low distortion to meet ADC aperture uncertainty and SNR requirements. Use Value: 560 V/µs slew rate prevents missing codes during full-scale transitions; rail-to-rail output matches ADC input range without external level shift. |
| Portable Systems | High-Density Systems |
Use Scenario: Signal conditioning in wearable ECG monitors and glucose meters where PCB area and battery life are constrained. IC Role / Device Role / Timing Role: Dual op-amp replaces two discrete single-channel devices, reducing component count and layout complexity. Use Value: SOIC-8 footprint fits tight spaces; 2.5 V minimum supply enables direct connection to buck-converted 3.3 V or LDO-regulated 2.8 V rails. |
Use Scenario: Multi-channel sensor fusion in industrial PLC I/O modules requiring simultaneous analog signal processing. IC Role / Device Role / Timing Role: Two independent amplifiers condition separate sensor outputs (e.g., temperature + pressure) with minimal crosstalk (–120 dB). Use Value: Matched DC specs (±65 µV offset) and thermal tracking ensure consistent channel-to-channel accuracy across temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2835IDGKR | Lower bandwidth (30 MHz), lower quiescent current (0.25 mA/channel), same SOIC-8 footprint but VSSOP-10 package | Better suited for sub-MHz precision sensing; insufficient for >10 MSPS ADC driving | Select when power budget < 0.3 mA/channel dominates over speed; verify layout compatibility with VSSOP-10 |
| LMH6619MMX/NOPB | Higher quiescent current (1.25 mA/channel), rail-to-rail input/output, 140 MHz bandwidth, MSOP-8 package | Superior input stage for true rail-to-rail input; less optimal for negative-rail input scenarios | Choose when input common-mode must extend to VS− and VS+, not just VS−; confirm thermal derating for continuous 1.25 mA/channel |
Compared with OPA2836IDR, OPA2835IDGKR trades 85% bandwidth for 75% lower power, while LMH6619MMX/NOPB adds rail-to-rail input capability at the cost of 25% lower bandwidth and no negative-rail input optimization - making OPA2836IDR uniquely balanced for portable high-speed signal chains.

FAQ
What is the maximum supply voltage for OPA2836IDR?
The OPA2836IDR supports a maximum supply voltage of 5.5 V across VS+ and VS− terminals, with absolute maximum ratings specifying VS+ to VS− ≤ 5.5 V. Operation beyond this risks permanent damage. Recommended operating range is 2.5 V to 5.5 V, and the device is fully characterized at 2.7 V and 5 V supplies per its datasheet electrical tables.
Does OPA2836IDR support single-supply operation?
Yes, OPA2836IDR supports true single-supply operation from 2.5 V to 5.5 V, with VS− connected to ground and VS+ tied to the positive rail. Its negative-rail input stage accepts common-mode voltages down to –0.2 V (at 5 V supply), and rail-to-rail output swings within 20 mV of both rails - enabling full-swing signal handling without dual supplies.
What is the purpose of the PD1 and PD2 pins on OPA2836IDR?
PD1 and PD2 are independent power-down control inputs for each amplifier channel. Driving either pin low (≤0.7 V) places its respective amplifier into ultra-low-power shutdown mode, reducing quiescent current to 0.5 µA typical. Both pins must be driven actively - floating is undefined - and require logic-level compatible voltage sources per the datasheet's enable/disable thresholds.
Can OPA2836IDR drive a 50-Ω load directly?
No, OPA2836IDR is not specified to drive 50-Ω loads continuously. Its output current rating is ±45 mA into higher-impedance loads (e.g., 1 kΩ), and driving 50 Ω would demand ±100 mA at 5 V - exceeding its safe operating area. For 50-Ω interface, use a dedicated line driver or add a series resistor to limit current while preserving signal integrity.
What is the input common-mode voltage range for OPA2836IDR at 5-V supply?
At a 5-V supply (VS+ = 5 V, VS− = 0 V), the OPA2836IDR input common-mode voltage range is –0.2 V to +3.9 V, verified under conditions where CMRR degradation remains below 3 dB. This negative-rail input capability allows direct interfacing with signals referenced below ground, such as transducer outputs or AC-coupled stages, without level-shifting circuitry.
