The VCA710 is a single-channel, low-noise, low-power variable gain analog front end (AFE) optimized for high-performance signal conditioning. The VCA710 integrates two sub-blocks: a low-noise amplifier (LNA) with a fixed gain of 10V/V (20dB) and a variable gain amplifier (VGA) delivering high dynamic range and gain control flexibility. The LNA and the VGA blocks can be used independently or in conjunction based on the requirement.

The VGA sub-block features a High Gain and Low Gain mode offering two gain ranges: –12dB to +40dB or –32dB to +20dB for optimizing output noise. The VGA supports both AC and DC coupled inputs as well as single-ended and differential inputs. The VCA710 features a fully differential output with an adjustable output common mode control feature.

The VCA710 supports a wide-supply from 3.15V to 5.25V, temperature range of –55°C to +125°C, in a compact 3.5mm × 3.5mm 20-pin RGR (VQFN) package. The VCA710 is an excellent choice for applications like ultrasound, sonar, optoelectronic front-ends.
