[[File:A2DM14_top_rotated.jpeg|thumb|ICE-A2D-M14 Top]] [[File:A2DM14 bottom.jpeg|thumb|ICE-A2D-M14 Bottom]] The ICE A2D-M14 is a 14-bit A/D module for use with the [[ICE-PIC5XL|ICE-PIC5]], [[ICE-PIC6]], [[ICE-PIC7]], and [[ICE-PIC8]] series of high-speed interface cards. (The latter is recommended.)

Software selection allows for the use of an onboard clock synthesizer or direct clock input at a user desired sample rate. The onboard clock synthesizer uses a 10MHz reference from either an external source (J2) or via an onboard oscillator (TCXO).

The A2D-M14 module incorporates a variable gain input stage, which allows for real-time gain settings of -11dB to +20dB in 1dB steps and is user-software controlled. Additionally, the variable gain stage can be used to mute or to disable completely analog input to the A/D.

The use of external 10 MHz and 1 PPS reference signals allows for precision time stamping of digitized data with better than 2.5 nanosecond accuracy, independent of sample rate.
