Product details
Overview
OPA2836IDGSR 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 unity-gain 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 serves as a high-speed, low-power ADC driver in portable instrumentation and battery-powered signal chains.
For engineers reviewing the OPA2836IDGSR datasheet, OPA2836IDGSR pinout, OPA2836IDGSR application, or OPA2836IDGSR equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases for SAR/ΔΣ ADC interfaces, and validated alternative options with documented functional and layout implications.
Technical Context
The OPA2836IDGSR implements a voltage-feedback architecture optimized for wideband operation with minimal power penalty. Its negative-rail input stage enables true single-supply operation down to –0.2 V (with 5-V supply), while rail-to-rail output swing supports full dynamic range utilization across 2.5–5.5 V supplies.
Each amplifier features independent power-down control (PD1/PD2 pins), reducing quiescent current to 0.5 µA per channel in shutdown. The device maintains 116 dB CMRR and 4.6 nV/√Hz input voltage noise at 100 kHz, enabling precision high-frequency signal conditioning without performance trade-offs.

| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT1 | Amplifier 1 output - rail-to-rail swing, capable of sourcing/sinking ±45 mA |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2835IDGSR | 30 MHz bandwidth, 0.25 mA IQ per channel - lower speed, 75% less power | Targeted at sub-100 kSPS precision sensing, not high-speed ADC driving | Select when bandwidth demand < 50 MHz and ultra-low IQ dominates design priority |
| LMH6619MMX/NOPB | 140 MHz bandwidth, 1.25 mA IQ, rail-to-rail input/output - wider input range but higher power | Supports true rail-to-rail input; better for AC-coupled or bipolar input signal chains | Choose when input common-mode must span full supply; accept 25% higher IQ for input flexibility |
Compared with OPA2836IDGSR, OPA2835IDGSR trades bandwidth for power efficiency, while LMH6619MMX/NOPB adds rail-to-rail input capability at higher quiescent current - neither is pin-compatible, requiring layout revision for substitution.

FAQ
What is the maximum supply voltage for OPA2836IDGSR?
The absolute maximum supply voltage (VS+ to VS−) for OPA2836IDGSR is 5.5 V. Operation beyond this risks permanent damage. Recommended operating range is 2.5 V to 5.5 V, with tested performance across that span including 205 MHz bandwidth at 5 V and 200 MHz at 2.7 V. Always maintain VS+ and VS− within these limits during power-up sequencing.
Does OPA2836IDGSR support true single-supply operation?
Yes, OPA2836IDGSR supports true single-supply operation from 2.5 V to 5.5 V. Its negative-rail input stage accepts common-mode voltages down to –0.2 V (with 5-V supply), and rail-to-rail output swings within 80 mV of VS+ and 40 mV of VS−. This eliminates need for dual supplies or external level shifters in most sensor and ADC interface applications.
What is the power-down behavior of OPA2836IDGSR?
OPA2836IDGSR has independent PD1 and PD2 pins controlling each amplifier. Driving either pin low (≤0.7 V) reduces its quiescent current to 0.5 µA typical. Output enters high-impedance state, and turnoff delay is 25 ns. Turnon delay is 200 ns. Both channels must be enabled for dual-channel operation; partial shutdown saves power without affecting active channel performance.
Can OPA2836IDGSR drive a 50-Ω load directly?
OPA2836IDGSR can source/sink ±45 mA, sufficient to drive a 50-Ω load to ±2.25 V with headroom. However, sustained 50-Ω loading increases junction temperature and may degrade distortion and bandwidth. For continuous 50-Ω operation, verify thermal margin using RθJA = 150.1°C/W and derate output current per TI's SOIC thermal guidelines. Use series termination if DC accuracy is critical.
Is OPA2836IDGSR suitable for driving 16-bit SAR ADCs?
Yes, OPA2836IDGSR is well-suited for driving 16-bit SAR ADCs. Its 22 ns 0.1% settling time meets timing requirements for ≥10-MSPS converters, and –130 dBc THD preserves effective resolution. With 4.6 nV/√Hz noise and 116 dB CMRR, it maintains SNR and rejects interference in precision acquisition systems - confirmed in TI's typical application circuits for ADS88xx and similar devices.
