Product details
Overview
OPA4336EA/250 from Texas Instruments is a quad, single-supply, microPower CMOS operational amplifier optimized for battery-powered instrumentation. It delivers rail-to-rail output swing within 3mV of the rails, 125µV max input offset voltage, and ultra-low 20µA per-amplifier quiescent current across 2.3V–5.5V supply range-enabling precision signal conditioning in portable medical devices and photodiode pre-amplifiers.
For engineers reviewing the OPA4336EA/250 datasheet, OPA4336EA/250 pinout, OPA4336EA/250 application, or OPA4336EA/250 equivalent, key selection criteria include its SSOP-16 package footprint, guaranteed –40°C to +85°C operation, low 1pA input bias current for high-impedance sensor interfaces, and unity-gain stability with capacitive load drive up to 300pF.
Technical Context
The OPA4336EA/250 implements a CMOS input stage with rail-to-rail output architecture, enabling full-swing operation from V– to within 3mV of V+ under 100kΩ load. Its common-mode input range extends to (V–) –0.2V, supporting true single-supply operation without level-shifting circuitry.
Each of the four independent amplifiers features 115dB open-loop gain, 100kHz gain-bandwidth product, and 0.03V/µs slew rate-optimized for low-frequency precision applications like integrators and sensor front-ends where power efficiency and dc accuracy dominate over speed.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher 550µA per-amp quiescent current; 6mV output swing; 2.5V min supply | Not suitable for coin-cell or multi-year battery life; better for higher-speed 1MHz GBW needs | Select when bandwidth >100kHz is required and power budget allows >2mA total supply current |
| OPA4340UA | 250µA per-amp IQ; rail-to-rail I/O; 1MHz GBW; 100µV offset | Higher power consumption trades for faster settling in data acquisition systems | Choose for 12-bit+ SAR ADC driving where 0.01% linearity must be maintained at 100ksps sampling rates |
Compared with TLV2464IDR and OPA4340UA, the OPA4336EA/250 uniquely balances ultra-low power (20µA/amp), precision (125µV offset), and rail-to-rail output in a quad configuration-making it irreplaceable for battery-critical, low-frequency sensor signal chains where every nanoamp counts.

FAQ
What is the maximum operating temperature range for the OPA4336EA/250?
The OPA4336EA/250 is specified over –40°C to +85°C for full parameter compliance, with extended operation possible from –55°C to +125°C. This makes the OPA4336EA/250 suitable for industrial environments and automotive cabin applications where ambient temperatures exceed standard commercial ranges.
Does the OPA4336EA/250 require external compensation for unity-gain stability?
No, the OPA4336EA/250 is internally compensated and unity-gain stable. It operates reliably in G=1 configurations without external capacitors, though a 50Ω–100Ω series resistor in the feedback loop is recommended when driving >300pF capacitive loads to maintain phase margin.
What is the input common-mode voltage range of the OPA4336EA/250?
The OPA4336EA/250 supports an input common-mode range from (V–) –0.2V to (V+) –1V. This extends below ground in single-supply systems, enabling accurate amplification of signals near the negative rail-critical for sensor interfaces with bipolar output swings referenced to ground.
Can the OPA4336EA/250 drive a 10kΩ resistive load while maintaining rail-to-rail output?
Yes-the OPA4336EA/250 maintains rail-to-rail output swing within 20mV of the rails into a 25kΩ load and within 100mV into a 5kΩ load. For a 10kΩ load, output swing remains within ~50mV of the rails, preserving >98% of full-scale dynamic range at 3.3V supply.
Is the OPA4336EA/250 RoHS compliant and what is its moisture sensitivity level?
Yes, the OPA4336EA/250 is RoHS compliant and carries a Moisture Sensitivity Level (MSL) rating of Level-2-260C-1 YEAR. This requires baking before reflow if exposed to ambient conditions beyond 1 year, per JEDEC J-STD-020 standards.
