Product details
Overview
OPA2336E/250 from Texas Instruments is a dual, rail-to-rail output, microPower CMOS operational amplifier designed for single-supply battery-powered systems. It delivers 125 µV max input offset voltage, 20 µA per amplifier quiescent current, and rail-to-rail output swing within 3 mV of supply rails at 100 kΩ load - enabling precision signal conditioning in portable medical instruments and photodiode pre-amplifiers.
For engineers reviewing the OPA2336E/250 datasheet, OPA2336E/250 pinout, OPA2336E/250 application, or OPA2336E/250 equivalent, key selection criteria include its 2.3 V to 5.5 V operating range, 1 pA input bias current, 115 dB open-loop gain, and MSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The OPA2336E/250 implements a CMOS input stage with rail-to-rail output stage, supporting common-mode input down to the negative rail (V–) and output swing to within 3 mV of both supply rails. Its unity-gain stable architecture enables direct use in precision integrators and high-impedance sensor interfaces without external compensation.
Each amplifier operates independently with no crosstalk, leveraging fully isolated circuitry across dual channels. The device maintains specified performance over –40°C to +85°C and supports operation from –55°C to +125°C, with thermal resistance θJA = 150°C/W in the MSOP-8 package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA/2K5 | Higher quiescent current (550 µA vs 40 µA), wider GBW (5.5 MHz), rail-to-rail input/output | Requires higher power budget but supports AC-coupled audio and faster settling | Select when bandwidth >100 kHz or rail-to-rail input is mandatory; avoid for multi-year battery life targets |
| MCP6022-I/SN | Lower offset (250 µV typ vs 125 µV max), higher IQ (100 µA vs 40 µA), same MSOP-8 package | Suitable for cost-sensitive industrial controls where 0.05% accuracy suffices | Choose for price-sensitive volume production; verify offset drift tolerance in medical-grade designs |
Compared with OPA2336E/250, the OPA2340UA/2K5 trades 27× higher supply current for 55× greater bandwidth, while the MCP6022-I/SN offers lower cost at the expense of guaranteed offset and ultra-low IQ - making OPA2336E/250 optimal for long-life, precision, single-supply instrumentation.

FAQ
What is the maximum operating temperature range for the OPA2336E/250?
The OPA2336E/250 is specified over –40°C to +85°C for full parameter compliance, and operates reliably from –55°C to +125°C. Its thermal resistance (θJA = 150°C/W in MSOP-8) ensures safe junction temperatures under typical PCB copper pour conditions at ambient up to +85°C. Always consult TI's SBOS068C datasheet for derating curves.
Does the OPA2336E/250 support rail-to-rail input operation?
No, the OPA2336E/250 features rail-to-rail *output* only. Its input common-mode range extends from (V–) –0.2 V to (V+) –1 V - meaning it accepts signals down to the negative rail but not up to the positive rail. For true rail-to-rail input, consider TI's OPA2340 or OPA2727 families. This limitation is explicitly documented in the Electrical Characteristics table on page 3 of SBOS068C.
Can the OPA2336E/250 drive capacitive loads, and what is the recommended approach?
Yes, the OPA2336E/250 can drive capacitive loads up to ~300 pF in unity-gain configuration. For larger loads, TI recommends inserting a 50–100 Ω resistor inside the feedback loop (between output and inverting input) to maintain stability - as shown in Figure 3 of SBOS068C. This preserves DC accuracy while suppressing ringing, especially critical in photodiode transimpedance applications where CL exceeds 100 pF.
What is the part marking for OPA2336E/250, and how is it identified on the package?
The OPA2336E/250 is marked "B36" on the top surface of its MSOP-8 (DGK) package, per TI's Package Option Addendum. This marking appears alongside TI logo and date code. The "B36" identifier distinguishes it from other OPA2336 variants (e.g., OPA2336U uses "OPA2336U") and confirms the DGK package and temperature grade (–40°C to +85°C).
Is the OPA2336E/250 RoHS compliant and lead-free?
Yes, the OPA2336E/250 is RoHS compliant and lead-free, as confirmed in TI's Package Option Addendum (status: Active, RoHS = Yes). Its lead finish is specified as "Call TI", indicating standard NiPdAu or matte tin depending on batch - both fully compliant with JEDEC J-STD-609 and EU RoHS Directive 2011/65/EU. MSL rating is Level-2-260C-1 YEAR.
