VCA-9 Configurable Mixed Signal Array
VCA-9 is a high-voltage, Via-Configurable Array (VCA) that contains 47 op-amps (30 of which operate at up to 20V), 3 Analog to Digital Converters (ADCs), 2 Digital to Analog Converters (DACs), supporting analog resources, and configurable logic gates (refer to diagram in right column).
The analog I/O pads and internal analog resources are capable of operation at up to 20V, making this VCA an excellent fit for higher voltage applications. The balanced mix of op amps, data converters, and digital resources enable the design of analog filters, multi-channel data-acquisition circuits, and other mixed-signal processing applications. This VCA is perfectly suited to sweep up mixed-signal circuits that contain Analog Front-End (AFE) functions that require digital interfaces to devices such as FPGAs, DSPs, and microcontrollers. Applications include control loops, power management and sequencing, as well as simply integrating analog and digital glue functions.
Like all of Triad’s configurable devices, VCA-9 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.
