What are the key features of OPA357AIDDAG3?

  • 250 MHz gain-bandwidth product enabling high-speed signal conditioning in optical and communications circuits
  • Rail-to-rail input and output swing on a 2.7 V to 5 V single supply for low-voltage system design
  • Ultra-low 50 fA input bias current minimizing error in high-impedance sensor interfaces
  • 80 dB CMRR with internal frequency compensation for stable operation without external compensation networks

What is OPA357AIDDAG3 used for?

The OPA357AIDDAG3 is used in high-speed photodiode transimpedance amplifiers, optical receiver front-ends, and active filter stages where 250 MHz bandwidth and rail-to-rail output swing are required on a single 3.3 V or 5 V supply. Its 50 fA input bias current makes it suitable for charge amplifiers, pH electrode interfaces, and picoampere-level current measurement circuits. It also serves in video signal buffering and ADC driver stages requiring low distortion at signal frequencies up to 100 MHz.

Frequently Asked Questions

What gain-bandwidth product does the OPA357AIDDAG3 provide, and at which supply voltage?

The OPA357AIDDAG3 has a gain-bandwidth product of 250 MHz, measured on a single supply of 2.7 V to 5 V. This bandwidth supports transimpedance amplifier designs with feedback resistors up to 10 kΩ while maintaining a closed-loop bandwidth above 25 MHz, suitable for optical data link receiver front-ends.

How does the 50 fA input bias current of the OPA357AIDDAG3 compare to bipolar op-amps in sensor interfaces?

At 50 fA (0.00005 pA), the OPA357AIDDAG3 input bias current is roughly 6 orders of magnitude lower than typical bipolar op-amps that measure 100 nA to 1 µA. This means a 1 MΩ feedback resistor in a transimpedance configuration introduces less than 0.05 µV of bias-current-induced offset error, enabling accurate measurement of sub-nanoampere photodiode or pH electrode currents.

Can the OPA357AIDDAG3 drive an ADC input directly in a 3.3 V single-supply design?

Yes. The OPA357AIDDAG3 rail-to-rail output stage swings to within approximately 50 mV of each supply rail on a 3.3 V single supply, providing an effective output range of 0.05 V to 3.25 V. This covers the full input range of most 12-bit or 16-bit successive approximation ADCs powered from 3.3 V without requiring a level-shift network between the amplifier and the converter.

What packaging does the OPA357AIDDAG3 use, and how does it compare to SOT-23 for space-constrained designs?

The OPA357AIDDAG3 uses the SC70-5 package, which measures approximately 2.0 mm x 2.1 mm — about 30% smaller in board footprint than the SOT-23-5 package at 2.9 mm x 1.6 mm. This size advantage makes it suitable for wearable medical sensors, handheld instruments, and compact optical modules where component density exceeds 200 parts per 100 cm².
