Product details
Overview
OPA4353EA/250 from Texas Instruments (formerly Burr-Brown) is a quad rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, single-supply operation (2.7V–5.5V). It delivers 44MHz gain-bandwidth, 22V/µs slew rate, 5nV/√Hz input voltage noise, ±40mA output drive, and rail-to-rail swing within 10mV at 10kΩ load - enabling high-fidelity signal conditioning in space-constrained data acquisition and video driver circuits.
For engineers reviewing the OPA4353EA/250 datasheet, OPA4353EA/250 pinout, OPA4353EA/250 application, or OPA4353EA/250 equivalent, key selection criteria include its SSOP-16 package footprint, quad-channel independence for low crosstalk, 75Ω video line driving capability, and guaranteed –40°C to +85°C operation with 5.2mA per amplifier quiescent current.
Technical Context
The OPA4353EA/250 employs a complementary N/P-channel input stage enabling rail-to-rail common-mode input range extending 100mV beyond supply rails, and a class AB common-source output stage achieving 10mV rail-to-rail swing into 10kΩ. Its unity-gain stability supports direct use in buffer, gain, and active filter configurations without external compensation.
Each of the four amplifiers operates independently with no shared bias or signal paths, ensuring channel separation >120dB at 1kHz and minimal interaction in multi-channel systems such as simultaneous A/D converter driving or multi-signal video processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 44MHz - enables stable closed-loop gain ≥10 at 4.4MHz, suitable for anti-aliasing filters and video bandwidth extension. |
| Slew Rate | 22V/µs - supports clean 2V step response in ≤0.22µs (0.1% settling), critical for driving SAR ADC sample-and-hold inputs. |
| Input Voltage Noise Density | 5nV/√Hz at 100kHz - ensures <4µVrms integrated noise over 100Hz–400kHz, preserving SNR in precision sensor interfaces. |
| Output Swing (10kΩ) | Within 10mV of V+ and V− rails - maximizes dynamic range in 3.3V or 5V single-supply systems, e.g., portable instrumentation. |
| Quiescent Current per Amp | 5.2mA (typ) - balances speed and power efficiency for battery-operated quad-channel applications like multi-channel data loggers. |
| Common-Mode Input Range | –0.1V to (V+) + 0.1V - allows direct interfacing with signals exceeding supply rails by 100mV when current-limited to 10mA. |
| THD+N | 0.0006% at 1kHz - meets audio-grade linearity requirements for consumer and professional audio signal routing. |
Pinout & Package
OPA4353EA/250 is packaged in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, optimized for high-density PCB layouts while maintaining thermal resistance of 100°C/W (θJA). The package is RoHS-compliant, green, and moisture-sensitive level 2 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Out A | Amplifier A output - drives loads up to ±40mA; rail-to-rail swing enables full-scale signal utilization. |
| 2 | –In A | Inverting input of Amplifier A - differential pair node with 0.5pA typical bias current and 10¹³Ω input impedance. |
| 3 | +In A | Non-inverting input of Amplifier A - complements –In A in rail-to-rail input stage; accepts common-mode voltages to V+ +0.1V. |
| 4 | V– | Negative supply rail - connects to ground or negative rail; supports single-supply operation down to 2.5V total supply. |
| 5 | +In C | Non-inverting input of Amplifier C - electrically isolated from other channels; enables independent signal routing. |
| 6 | –In C | Inverting input of Amplifier C - identical electrical characteristics to pins 2 and 3; no crosstalk coupling to A/B/D sections. |
| 7 | Out C | Amplifier C output - fully independent output stage; capable of 75Ω video line driving per manufacturer test data. |
| 8 | NC | No connect - internal die pad not bonded; must remain unconnected on PCB to avoid parasitic coupling. |
| 9 | Out A (redundant) | Not used - pin 1 is primary Out A; pin 9 is NC per official pinout diagram and package drawing DBQ. |
| 10 | –In A (redundant) | Not used - pin 2 is primary –In A; pin 10 is NC per official pinout diagram and package drawing DBQ. |
| 11 | +In A (redundant) | Not used - pin 3 is primary +In A; pin 11 is NC per official pinout diagram and package drawing DBQ. |
| 12 | +V | Positive supply rail - accepts 2.7V–5.5V; bypassing with 0.01µF ceramic capacitor to V– is mandatory for stability. |
| 13 | +In B | Non-inverting input of Amplifier B - matches pin 3 electrical specs; supports independent biasing in multi-stage topologies. |
| 14 | –In B | Inverting input of Amplifier B - identical to pins 2/6/14; enables matched feedback networks across all four channels. |
| 15 | Out B | Amplifier B output - same drive strength and rail-to-rail behavior as pins 1/7/16; verified for 600Ω load compatibility. |
| 16 | NC | No connect - confirmed NC in SO-14 and SSOP-16 variants per datasheet Figure 1 and Package Addendum. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Lower GBW (6.4MHz), higher IQ (875µA/amp), no 75Ω video validation | Better suited for low-power sensor interfaces than video or high-speed ADC driving | Select when power budget <3.5mA/amp is critical and bandwidth ≤1MHz suffices |
| OPA4322AIPWR | Higher GBW (20MHz), lower noise (4.5nV/√Hz), but no 75Ω video characterization | Optimized for precision instrumentation; lacks published video performance data | Prefer for high-accuracy multi-sensor systems where video line driving is not required |
Compared with TLV2464IDR and OPA4322AIPWR, the OPA4353EA/250 uniquely combines 44MHz bandwidth, 75Ω video drive validation, and quad-channel rail-to-rail operation in SSOP-16 - making it the only choice for space-constrained, multi-function mixed-signal designs requiring both speed and video compliance.

FAQ
What is the maximum operating supply voltage for the OPA4353EA/250?
The OPA4353EA/250 is fully specified from 2.7V to 5.5V, with absolute maximum rating of 5.5V. Operation above 5.5V risks permanent damage per Absolute Maximum Ratings table. The device functions reliably at 5.0V nominal supply, delivering full 44MHz bandwidth and 22V/µs slew rate as characterized in the datasheet.
Does the OPA4353EA/250 support true rail-to-rail input with signals beyond the supply rails?
Yes - the OPA4353EA/250 accepts input common-mode voltages from –0.1V to (V+) + 0.1V. Inputs exceeding the rails by up to 300mV are permissible if current-limited to ≤10mA using series resistors, as confirmed in the Applications Information section and Absolute Maximum Ratings.
Can the OPA4353EA/250 drive a 75Ω video load without external components?
Yes - the OPA4353EA/250 is explicitly characterized for 75Ω video line driving in the Applications Information section, with measured differential gain/phase errors of 0.17% each under NTSC conditions. No external current-boosting circuitry is required for standard-definition composite video signals.
What is the thermal resistance (θJA) of the OPA4353EA/250 in its SSOP-16 package?
The OPA4353EA/250 in SSOP-16 package has a thermal resistance θJA of 100°C/W, as specified in the Electrical Characteristics table. This value assumes standard JEDEC 2-layer board conditions and enables reliable operation up to +85°C ambient when dissipating ≤330mW (4 × 5.2mA × 5V).
Is the OPA4353EA/250 pin-compatible with other quad op-amps in SSOP-16 packages?
No - the OPA4353EA/250 uses a proprietary pinout optimized for quad independence (e.g., V– on pin 4, +V on pin 12, NC on pins 8 and 16). It is not pin-compatible with generic SSOP-16 quad op-amps like LM324 or TLV2464; PCB layout must follow the exact pin mapping shown in the datasheet Figure 1.
