Technologic Systems TS-9700 Accessory with 12-bit A/D with 0.2% accurate Vref, 12-bit DAC optional Simple Type: Accessory

The Technologic Systems TS-9700 is a PC/104 daughter board that provides 8 channels of 12-bit Analog-to-Digital (A/D) conversion using a precision 0.2% analog reference. A single Analog Devices AD7888 chip implements the heart of the A/D subsystem. Each analog input can be individually jumper selected for one of three ranges: 0 – 2.5 Volt 0 – 10.0 Volt 0 – 20 mA The Analog-to-Digital conversion takes 9 microseconds to complete allowing up to 100K samples per second. The TS-9700 can optionally be populated with 4 channels of 12-bit digital-to-analog conversion using a 0.2% analog reference. Two Texas Instruments TLV5818 chips are used to implement the four Digital-to-Analog converter (DAC) outputs. Each DAC output has a rail-to-rail output buffer that allows a nominal 0 to 5 Volt output swing using a single 5V power supply.
