1. INTRODUCTION

The Hytec IP-ADC-8424 is an Industry Pack that provides 4 channels of simultaneously

sampled analogue digitisation with the following characteristics:-

• 4 independent channels (one ADC per input).

• True full differential inputs.

• Up to 1MHz sampling rate.

• Input impedance - 10Mohms differential.

• Resolution - 16 bits no missing codes.

• Accuracy - 14 bits.

• On board RAM Memory 1M x 16 bits (256K conversions per channel).

• Programmable full-scale resolution all inputs +/-10V or +/-5V.

• On-board calibration by FPGA firmware using stored offset and gain.

• Gain drift - 4ppm per deg C (typ).

• Offset drift - +/-10uV/degC (typ).

• +/-10V offset error - +/-2LSBs with firmware calibration (+/- 2mV without calibration).

• +/-5V offset error - +/-4LSBs with firmware calibration (+/- 2mV without calibration).

• +/-10V gain error - +/-2LSBs with firmware calibration (+/- 5mV without calibration).

• +/-5V gain error - +/-4LSBs with firmware calibration (+/- 4mV without calibration).

• ADC voltage reference drift - 2.0ppm/

C (max).

• CMRR: - 100dB at +/-5V wrt plant CMV (92db typical at 100KHz).

• Aperture Delay - 15 ns typ.

• Aperture Delay Matching - 70 ps typ.

• Aperture Jitter - 50 ps typ.

• Over voltage - +/-25V on or off.

• On-board sample clock programmable (1MHz, 500KHz, 200KHz, 100KHz, 50KHz,

20KHz,10KHz, 5KHz, 2KHz, 1KHz, 500Hz, 200Hz,100Hz, 50Hz, 20Hz,10Hz,

5Hz, 2Hz and 1Hz).

• Ext sample clock isolated input.

• Ext trigger isolated input.

• System to plant isolation to 100V when externally powered by DC/DC converter option.

• Board type, Serial number, PCB issue and firmware issue held in ID PROM.

• 8/32MHz IP system clock operation.

• Field upgradeable firmware (requires Xilinx/compatible device to program built in FPGA flash

memory via the FPGA JTAG port).

• EPICS and ASYN driver support.

• PCB temperature measurement via onboard chip.
