Product details
Overview
OPA2836IDGS 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 is designed for high-frequency signal conditioning in portable, low-power, and high-density systems.
For engineers reviewing the OPA2836IDGS datasheet, OPA2836IDGS pinout, OPA2836IDGS application, or OPA2836IDGS equivalent, key selection criteria include its 205 MHz bandwidth with 1 mA power budget, rail-to-rail output swing, –0.2 V to +3.9 V input voltage range (5-V supply), and dual-channel crosstalk of –120 dB - all validated for industrial temperature operation.
Technical Context
The OPA2836IDGS implements a voltage-feedback architecture optimized for wideband, low-noise, low-power operation. Its internal design supports stable unity-gain configuration with 205 MHz bandwidth and preserves 116 dB CMRR across –40°C to +125°C, enabling precision AC-coupled and DC-coupled signal paths without external compensation.
It integrates independent power-down pins (PD1/PD2) per channel, reducing quiescent current to 0.5 µA per amplifier in shutdown mode while maintaining fast 200 ns turn-on and 25 ns turn-off timing. The device features a negative-rail input stage allowing operation with inputs down to –0.2 V (vs. VS–), supporting single-supply sensor interfaces and ADC driver topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 205 MHz at G = 1 - enables high-fidelity 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, critical for SAR ADC front-ends |
| Quiescent Current | 1 mA per channel - allows dual op-amp operation on coin-cell or energy-harvested supplies |
| Input Voltage Range | –0.2 V to +3.9 V (5-V supply) - accepts signals below ground, simplifying level-shifting in single-supply systems |
| Output Drive | ±45 mA - drives 1-kΩ loads directly into rail-to-rail output swing with <80 mV saturation voltage |
| THD + Noise | –130 dBc THD & –117.6 dBc SNR at 1 kHz - meets audio-grade and high-resolution ADC buffer requirements |
| Crosstalk | –120 dB at 10 kHz - ensures isolation between channels in dual-signal-path applications like stereo audio or differential sensing |
Pinout & Package
The OPA2836IDGS is packaged in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained PCB layouts while maintaining thermal performance (RθJA = 206°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1– | Inverting input, Channel 1 | Accepts differential or inverting configurations; supports common-mode down to –0.2 V |
| VIN1+ | Noninverting input, Channel 1 | High-impedance node (100 MΩ || pF); used for unity-gain buffers or active filters |
| VOUT1 | Output, Channel 1 | Rail-to-rail swing (0.2 V to 2.5 V on 2.7 V supply); drives ≥2 kΩ loads with <0.1% settling in 30 ns |
| VS– | Negative supply | Reference for both inputs and outputs; enables true negative-rail input operation |
| VIN2+ | Noninverting input, Channel 2 | Independent of Channel 1; enables dual-path signal processing with minimal interaction |
| VIN2– | Inverting input, Channel 2 | Matches Channel 1 specs; supports matched gain-setting resistor networks in discrete configurations |
| VOUT2 | Output, Channel 2 | Identical performance to VOUT1; –120 dB crosstalk enables simultaneous high-speed acquisition |
| VS+ | Positive supply | Operates from 2.5 V to 5.5 V; PSRR of 108 dB rejects supply noise in battery-powered systems |
| PD1 | Power-down control, Channel 1 | Active-low logic input; pulls quiescent current to 0.5 µA when driven <0.7 V (VS– + 0.7 V) |
| PD2 | Power-down control, Channel 2 | Independent enable/disable per channel; supports dynamic power gating in multi-stage signal chains |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power with high speed | 205 MHz bandwidth at only 1 mA per channel - industry-leading power-to-performance ratio for rail-to-rail op-amps |
| Rail-to-rail output + negative-rail input | Output swings within 80 mV of rails; input accepts signals 0.2 V below VS– - eliminates level-shifting ICs in single-supply designs |
| Channel independence | –120 dB crosstalk at 10 kHz - enables dual-channel applications like I/Q demodulation or stereo buffering without interference |
| Fast power-down recovery | 200 ns turn-on / 25 ns turn-off - supports burst-mode operation in battery-powered data loggers and wireless sensors |
| Low distortion at high frequency | –85 dBc HD2 / –105 dBc HD3 at 1 MHz - preserves signal integrity in wideband ADC drivers and RF IF stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, high-speed operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2835IDGSR | Lower 30 MHz bandwidth, 0.25 mA quiescent current, same VSSOP-10 package | Better suited for sub-10 MHz precision sensor interfaces where power is more critical than speed | Select when bandwidth <50 MHz suffices and sub-300 µA/channel operation is mandatory |
| LMH6619MMX/NOPB | 140 MHz bandwidth, 1.25 mA IQ, rail-to-rail input/output, SOIC-8 package | Includes rail-to-rail input - advantageous for bipolar signal sources but consumes 25% more current | Choose when input common-mode range must span full supply and VSSOP footprint is not required |
Compared with OPA2836IDGS, OPA2835IDGSR trades 85% bandwidth for 75% lower power, while LMH6619MMX/NOPB adds rail-to-rail input capability at higher current and larger package - making OPA2836IDGS optimal for space-constrained, high-speed, single-supply applications demanding best-in-class bandwidth-per-mA.

FAQ
What is the maximum operating temperature for the OPA2836IDGS?
The OPA2836IDGS is fully specified and guaranteed to operate from –40°C to +125°C ambient temperature. Its electrical characteristics-including 116 dB CMRR, ±65 µV input offset, and 205 MHz bandwidth-are validated across this extended industrial temperature range, making it suitable for under-hood automotive sensors and industrial motor control environments.
Does the OPA2836IDGS support single-supply operation?
Yes, the OPA2836IDGS 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 relative to VS–, and its rail-to-rail output delivers full swing from near VS– to near VS+, enabling direct interfacing with microcontrollers and ADCs without level-shifting circuitry.
How does the power-down feature work on the OPA2836IDGS?
The OPA2836IDGS has two independent power-down pins: PD1 controls Channel 1 and PD2 controls Channel 2. Driving either pin low (<0.7 V above VS–) reduces that channel's quiescent current to 0.5 µA typical while preserving fast 25 ns turn-off and 200 ns turn-on response. Both pins must be actively driven-floating is undefined.
What is the input impedance of the OPA2836IDGS?
The OPA2836IDGS features 100 MΩ || pF common-mode input impedance and 100 kΩ || pF differential-mode input impedance at 100 kHz. These values remain stable across temperature and supply voltage, ensuring predictable loading of high-impedance sources such as piezoelectric sensors and photodiode transimpedance stages.
Can the OPA2836IDGS drive a 50-Ω load directly?
No, the OPA2836IDGS is not designed for direct 50-Ω termination. Its output is specified for ≥2 kΩ loads (±45 mA drive into 1 kΩ). For 50-Ω systems, use an external series resistor (e.g., 45 Ω) to isolate the op-amp while matching line impedance - this maintains stability and avoids excessive current draw beyond the ±45 mA absolute maximum rating.
