DescriptionThe VCA8500IRGCR is designed as an 8-channel variable gain amplifier consisting of a low-noise pre-amplifier (LNP) and a variable gain amplifier (VGA). This combination, along with the device features, makes it ideal for a variety of ultrasound systems.
VCA8500IRGCR has ten features. (1)Ultralow power: 65mW /channel. (2)Low noise: 0.8nV/Hz. (3)Low-noise pre-amp (LNP) which means 20dB fixed gain and 250mVpp linear input range. (4)Variable gain amplifier which means gain control range: 46dB, selectable PGA gain 20dB, 25dB, 27dB, 30dB, fast overload recovery and output clamping control. (5)Integrated low-pass filter: second-order, linear phase, bandwidth: 10MHz, 15MHz. (6)High accuracy which means low gain error: ±0.5dB and excellent channel matching: ±0.25dB. (7)Distortion, HD2: -50dBc at 5MHz. (8)Integrated CW switch matrix: easy current summing. (9)Serial control interface. (10)Small package: QFN-64, 9x9mm. That are all the main features.
Some absolute maximum ratings of VCA8500IRGCR have been concluded into several points as follow. (1)Its supply voltage range, AVDD1 would be from -0.3V to +3.9V. (2)Its supply voltage range, AVDD2 would be from -0.3 to +6V. (3)Its supply voltage range, DVDD would be from -0.3 to +3.9V. (4)Its voltage at analog inputs would be from -0.3 to (AVDD1+0.3)V. (5)Its voltage at digital inputs would be from -0.3 to (DVDD+0.3)V. (6)Its soldering temperature (lead, 5s) would be +260°C. (7)Its maximum junction temperature, any condition would be +150°C. (8)Its maximum junction temperature, continuous operation, long-term reliability would be +125°C. (9)Its storage temperature range would be from -55°C to +150°C. (10)Its operating temperature range would be from -40°C to +85°C. (11)Its ESD rating would be 2000V for human body model and would be 1000V for charged device model and would be 200V for machine model. And so on. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.
