The ADA4352-2 is a compact, monolithic, dual-channel, precision, programmable gain transimpedance amplifier (PGTIA). The ADA4352-2 is a breakthrough solution for precisely measuring small currents over a wide dynamic range. The precision of the ADA4352-2 over a wide temperature range of −40°C to +125°C enables users to perform one calibration of the end equipment at room temperature, thereby saving test time and cost. The ADA4352-2 integrates four current-to-voltage gain selections per channel, and the gain is programmable using two logic pins per channel to provide a flexible, fully functional compact PGTIA solution. Additionally, with its robust output stage and low noise, the ADA4352-2 can directly drive 16-bit precision analog-to-digital converters (ADCs, such as AD4696), providing a complete analog front-end (AFE) to address the most challenging precision current measurement applications.

The ADA4352-2 is offered in a 3 mm × 3 mm LFCSP, reducing the printed circuit board (PCB) area by up to 10 times relative to a discrete design using standalone operational amplifiers (op amps) and switches.

Applications

  • Precision current to voltage (I to V) conversion
  • Programmable gain TIAs
  • Photodetector interface and amplification
  • Optical networking equipment
  • Optical power measurement
  • Instrumentation—spectroscopy and chromatography
  • Precision data acquisition systems (DAQ)
