What are the key features of OPA4354AIDG4?
- 250 MHz gain-bandwidth product enabling high-speed signal amplification and active filtering up to tens of megahertz in quad-channel configurations
- Rail-to-rail input and output (RRIO) for maximum dynamic range from low single-supply voltages in portable and battery-powered systems
- Ultra-low input bias current of 0.00005 µA (50 pA) ideal for high-impedance CMOS and sensor interface circuits with minimal loading effects
What is OPA4354AIDG4 used for?
The OPA4354AIDG4 is designed for high-speed active filtering, signal buffering, and multi-channel ADC driver applications in communications, medical imaging, and industrial data acquisition systems requiring four simultaneous fast amplifier channels. Its 250 MHz bandwidth and rail-to-rail I/O allow efficient single-supply operation in portable instruments and battery-powered signal processing systems. The compact 14-pin SOIC package reduces per-channel PCB area compared to using four discrete single op-amps, simplifying board layout in multi-channel designs.

Frequently Asked Questions
What is the gain-bandwidth product of the OPA4354AIDG4, and what closed-loop bandwidth does it support at gain of 10?
The OPA4354AIDG4 has a gain-bandwidth product of 250 MHz. At a closed-loop gain of 10 V/V this yields approximately 25 MHz of usable signal bandwidth, and at a gain of 100 V/V the bandwidth drops to approximately 2.5 MHz. This makes it suitable for high-speed video amplifiers, active anti-aliasing filters, and wideband transimpedance stages in the 1 MHz to 50 MHz range.
How does the rail-to-rail input and output of the OPA4354AIDG4 benefit single-supply designs running from 3.3 V or 5 V?
The rail-to-rail input and output allows the OPA4354AIDG4 to process and output signals across nearly the full supply range, typically within 100 mV of either rail. On a 3.3 V supply this gives an output swing of approximately 3.1 V peak-to-peak, and on a 5 V supply approximately 4.8 V peak-to-peak, maximizing dynamic range without requiring a split supply. This is critical in ADC driver circuits where maximizing input range directly improves SNR.
For a 4-channel ultrasound front-end, how does the OPA4354AIDG4 compare to using four individual OPA354 single-channel op-amps?
The OPA4354AIDG4 integrates 4 channels into a single 14-pin SOIC package, reducing the total PCB footprint by approximately 60% compared to four separate OPA354 devices each in 8-pin SOT-23 or SOIC packages. It also reduces the bill of materials by 3 components, simplifying procurement and placement. The per-channel electrical performance including 250 MHz bandwidth and 50 pA bias current is equivalent to the single-channel OPA354.
What input offset voltage does the OPA4354AIDG4 have, and in which applications does this limit accuracy?
The OPA4354AIDG4 has a maximum input offset voltage of 10000 µV (10 mV) at room temperature. In a gain-of-10 stage this offset produces up to 100 mV of DC error at the output, which is acceptable for AC-coupled high-speed signal paths but may degrade accuracy in precision DC amplification. For DC-accurate applications requiring better than 1 mV output offset, a lower-offset alternative with Vos below 1 mV should be selected instead.
