VCA-10 Configurable Mixed Signal Array

VCA-10 is a high-voltage, Via-Configurable Array (VCA) that can operate at up to 20V.  Internal resources include over 2,200 20V FETs, 51 op-amps, 1 Analog to Digital Converter (ADC), 2 Digital to Analog Converters (DACs), supporting analog resources and configurable logic gates (refer to Figure 1).

VCA-10 is optimized for multi-channel designs requiring both high voltage and low voltage resources.  With over 2,200 20V transistors, 540 low voltage transistors, 51 op-amps and 3 data converters, multi-channel data acquisition solutions can be developed for 12V/24V automotive applications, portable medical devices and sensor interfaces.  The VCA also contains sufficient logic resources to develop a variety of serial or parallel digital interfaces.  In this way, VCA-10 can integrate existing analog front end components along with a digital interface to communicate with FPGAs/CPLDs and microcontrollers.  Additionally, 12K bits of onboard SRAM allows creation of customized memory elements such as RAMs and FIFOs for data storage and buffering.

Like all of Triad’s configurable devices, VCA-10 uses patented via-only, single-mask configuration allowing design changes in weeks rather than months, low development costs, reduced risk and support for any production volume.
