{{eolnotice|ICE-A2D-M20}}
The ICE-A2D-M18 is a dual-channel 12-bit analog-to-digital converter module for use with the [[ICE-PIC]] and [[ICEPOD]] series of high-speed interfaces.

The module is equipped with an onboard sample clock synthesizer, which can be configured to 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-M18 module incorporates a variable gain input stage. The variable gain stage allows independent channel gain settings from -40dB to +20dB in 1dB steps and is user software controlled. Additionally, the variable gain stage can be used to mute or completely disable 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.

== Features ==
* 12-bit resolution
* Dual-channel 1600 Megasamples/sec
* AC-coupled input
* Analog input nominal -20 dBm
* SFDR at max sample rate is > 65 dB
* 3dB sample and hold bandwidth 5 MHz – 2.7 GHz
* 12dB sample and hold bandwidth 1.2 MHz – 4.0 GHz
* External 1PPS input for precision time stamping of data
* Dual-site I/O module used with [[ICE-PIC]] series cards and [[ICEPOD]] subsystems

'''Notes:'''
# Operation using external reference of 10MHz replaces the external clock input. Sample clock is then generated from the 10MHz reference.
# Sample rates below 150 MSPS require decimation flag in module configuration.
