Features

A2D-r8 Functional Diagram
  • Utilizes TI ADS5424
  • 14-bit 105 MSamp/sec A/D converter 1Vp-p analog input range
  • Jumper-selectable AC- or DC-coupled analog input
  • External clock derived via a comparator, AC-coupled 1Vp-p
  • Oscillator socket (for user supplied clock, jumper selectable with external comparator clock)
  • External connector for 1-PPS LVTTL input-stored in bit 0 of 16 bit word (14-bit data MSB-aligned)
  • Over/underflow output on data bit 1 of 16-bit word (14-bit data MSB-aligned)

Note: For Use Only With ICE-PIC5XL or ICE-PIC6

Jumper Settings

DC- or AC-Coupled

Jumper DC-Coupled1 AC-Coupled2
J7 1 & 2 SHORT 2 & 3 SHORT
J8 1 & 2 SHORT 2 & 3 SHORT
J9 1 & 2 SHORT 2 & 3 SHORT

Notes:

  1. For sampling rates Of 2 MSPS and below, DC-coupling should be used.
  2. AC-coupled is the default setting when delivered.

Digital 3.3V Power Source

Jumper Voltage Regulator1 Board Header2
J3 1 & 2 SHORT OPEN
J4 1 & 2 SHORT 2 & 3 SHORT

Notes:

  1. 3.3V digital power via voltage regulator (default power setting when delivered)
  2. 3.3V digital power via board header (not an available source for the ICE-PIC3T or ICE-MBT3)

Analog 5V Power Source

Jumper Board Header1 External2
J2 2 & 3 SHORT 1 & 2 SHORT

Notes:

  1. 5V analog power via board header (default power setting when delivered)
    5V power is shared between digital logic and analog logic.
  2. 5V analog power via external power source:
    For normal operation, you will not need external power connections. Users who wish to supply the analog circuitry a "quieter" external power source, separate from the digital power connection as provided above, can connect to one or both pins of J2 a separate 5V supply.

Addendum:

  • For connecting to J2, Digi-Key supplies a terminal housing (Part Number: WM2601-ND).
  • You will also need 2 terminals for the housing (Part Number: WM2200-ND).
  • Wires: 22-30 AWG.

External Clock Selection

Jumper SMB Comparator1 User Supplied Oscillator2
J6 1 & 2 SHORT 2 & 3 SHORT

Notes:

  1. Default selection when delivered.
  2. User supplied oscillator—Oscillator (X4) should be 5V with CMOS output.
