Product details
Overview
OPA2836ID 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 - ideal for portable SAR ADC drivers and low-power signal conditioning in space-constrained industrial systems.
For engineers reviewing the OPA2836ID datasheet, OPA2836ID pinout, OPA2836ID application, or OPA2836ID equivalent, key selection criteria include its 205 MHz bandwidth at 1 mA/channel, rail-to-rail output swing with –0.2 V input capability, power-down mode (0.5 µA), and SOIC-8 package compatibility with high-density PCB layouts.
Technical Context
The OPA2836ID implements a voltage-feedback architecture optimized for wideband, low-power operation. Its internal design supports stable unity-gain configuration with 205 MHz bandwidth and achieves 22 ns settling time (0.1%) for 2-V step signals under 5-V supply conditions.
It features independent power-down pins (PD1/PD2) enabling per-amplifier shutdown, negative-rail input stage allowing operation down to VS– – 0.2 V, and rail-to-rail output delivering >99% of supply swing into 2-kΩ loads - all while maintaining 116 dB CMRR and 4.6 nV/√Hz input voltage noise at 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 205 MHz at AV = 1 - enables high-fidelity amplification of signals up to ~100 MHz without gain peaking or instability. |
| Slew Rate | 560 V/µs - supports clean reproduction of fast 2-V transitions in <3 ns with minimal distortion. |
| Quiescent Current | 1 mA per channel - allows dual-opamp operation on coin-cell or single-Li-ion supplies for >100-hour battery life. |
| Input Voltage Range | –0.2 V to +3.9 V (5-V supply) - accepts signals below ground, simplifying level-shifting in mixed-supply systems. |
| Output Drive | ±45 mA - drives 2-kΩ loads to rail with <80 mV saturation voltage, supporting direct interface to ADC inputs. |
| THD + Noise | 0.00003% (–130 dBc) at 1 kHz - meets 18-bit+ SAR ADC driver requirements with negligible harmonic contribution. |
| Power-Down Current | 0.5 µA typical - reduces system standby power by >99.9% per channel during idle periods. |
Pinout & Package
OPA2836ID is supplied in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, optimized for thermal performance (RθJA = 150.1°C/W) and automated assembly. Pin functions are validated per TI SLOS712J Rev J.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1+ | Amplifier 1 noninverting input | Accepts input signals down to –0.2 V relative to VS–; high-impedance node (100 MΩ || pF). |
| VIN1– | Amplifier 1 inverting input | Differential input pair node; used with feedback network to set closed-loop gain and stability. |
| VOUT1 | Amplifier 1 output | Rail-to-rail capable output driving ±45 mA; settles to 0.1% in 22 ns for 2-V step under 5-V supply. |
| VS– | Negative power supply input | Reference for both input common-mode range and output swing; supports single-supply (0 V) or split-supply (–2.75 V) operation. |
| VIN2+ | Amplifier 2 noninverting input | Independent input for second channel; shares same electrical specs and temperature range as Channel 1. |
| VIN2– | Amplifier 2 inverting input | Enables dual-channel signal processing with –120 dB crosstalk at 10 kHz - critical for multi-channel sensor interfaces. |
| VOUT2 | Amplifier 2 output | Matches VOUT1 performance; simultaneous dual-output operation supported without interaction. |
| VS+ | Positive power supply input | Accepts 2.5 V to 5.5 V; PSRR of 108 dB ensures immunity to supply ripple in noisy embedded environments. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power consumption | 1 mA per channel at 5 V enables dual-opamp integration in battery-powered devices without thermal derating. |
| High-speed precision | 205 MHz bandwidth + 4.6 nV/√Hz noise + –130 dBc THD enables 16–18-bit ADC front-end performance at DC–10 MHz. |
| True negative-rail input | Operates with inputs as low as –0.2 V (VS– referenced), eliminating need for level-shifting circuitry in single-supply systems. |
| Independent power-down control | Dedicated PD1 and PD2 pins allow selective shutdown of either amplifier, reducing system-level standby current to sub-µA levels. |
| Extended temperature operation | Specified from –40°C to +125°C with guaranteed offset drift ≤ ±1.1 µV/°C - suitable for automotive under-hood and industrial motor control. |
Applications

IC Role / Device Role / Timing Role: Dual-channel buffer and gain stage preceding audio ADC, handling differential mic bias and single-ended line-in paths. Use Value: 1 mA/channel quiescent current extends runtime; rail-to-rail output ensures full ADC input range utilization across 1.8–3.3 V supply variations. |
Use Scenario: 16-bit SAR ADC in handheld test equipment requiring fast settling and low noise. IC Role / Device Role / Timing Role: Driver amplifier providing gain, filtering, and drive strength to ADC input with <22 ns settling to 0.1%. Use Value: 205 MHz bandwidth and 560 V/µs slew rate enable accurate sampling of transient-rich waveforms without slewing-induced distortion. |

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 |
|---|---|---|---|
| OPA2835ID | 30 MHz bandwidth, 0.25 mA/channel, higher 9.3 nV/√Hz noise - trades speed/power for ultra-low quiescent current. | Better suited for sub-MHz sensor amplification where battery life dominates over bandwidth. | Select OPA2835ID only when bandwidth <50 MHz suffices and quiescent current must be <300 µA per channel. |
| LMH6619MM | 140 MHz bandwidth, 1.25 mA/channel, rail-to-rail input/output, but no power-down mode and wider SO PowerPAD package. | Preferred for high-precision, high-PSRR applications where input rail-to-rail is mandatory and thermal dissipation exceeds SOIC limits. | Choose LMH6619MM when input common-mode range must extend to both rails and thermal management requires exposed-pad packaging. |
Compared with OPA2836ID, OPA2835ID sacrifices bandwidth and noise performance for 75% lower quiescent current, while LMH6619MM offers rail-to-rail input at the cost of no power-down capability and larger thermal footprint - making OPA2836ID optimal for balanced high-speed, low-power, and space-constrained designs.

FAQ
What is the maximum operating supply voltage for the OPA2836ID?
The OPA2836ID supports a single-supply range of 2.5 V to 5.5 V or dual-supply operation from ±1.25 V to ±2.75 V. Absolute maximum supply voltage is 5.5 V between VS+ and VS–. Exceeding this risks permanent damage per TI's Absolute Maximum Ratings table in SLOS712J Rev J.
Does the OPA2836ID support rail-to-rail input operation?
No - the OPA2836ID features negative-rail input (down to VS– – 0.2 V) and rail-to-rail output, but its input common-mode range extends only to +3.9 V with a 5-V supply. For true rail-to-rail input, consider alternatives like OPA2365 or LMH6619, not the OPA2836ID.
How does the power-down function work on the OPA2836ID?
The OPA2836ID has dedicated PD1 and PD2 pins: driving either pin low (≤0.7 V above VS–) places its corresponding amplifier into ultra-low-power mode drawing 0.5 µA typical. Both pins must be driven high (>2.1 V above VS–) for normal operation. The pins require active logic-level control - floating is undefined.
What is the guaranteed settling time specification for the OPA2836ID?
At 5 V supply, the OPA2836ID achieves 22 ns settling time to 0.1% for a 2-V step output under G = 2 configuration. This value is characterized across –40°C to +125°C and appears in Section 7.7 of the official datasheet (SLOS712J Rev J, Table 7-11).
Which package variants are available for the OPA2836ID?
The OPA2836ID designation specifically refers to the 8-pin SOIC (D) package (4.90 mm × 3.91 mm). Other OPA2836 variants include VSSOP (DGS), WQFN (RUN), and UQFN (RMC) packages - but only the SOIC version carries the "ID" suffix per TI's orderable part numbering convention.
