    Here is the manufacturer's description...
    The LRS Model 2249A 12-Channel Analog-to-Digital Converter embodies all the operational characteristics which have proved important for general-purpose use in high energy particle physics, including expanded resolution (0.1%), higher sensitivity, excellent stability, faster digitizing rate, LAM and Q suppression, provision for fast clear, calibrating test mode, and flexible LAM options.
    These ADCs are specifically intended for use in demanding applications such as particle identification using de/dx counters, recording x-ray, neutron, or recoil proton energies using lead glass or other total energy absorption counters, improving time resolution by correcting for slewing due to variances in counter output amplitudes, monitoring gas threshold Cerenkov counters, and debugging or monitoring proportional or drift chambers.
    The Model 2249A contains twelve complete ADC's in a single-width CAMAC module. Each ADC offers a resolution of ten bits to provide 0.1% resolution over a wide 1024-channel dynamic range. The factor of 4 wider range allows operations with broad signal spectra such as are encountered in experiments anticipating fractionally charged particles or covering extensive energy ranges. It also greatly reduces the necessity for careful adjustment of signal strengths to match the limited range of an 8-bit, 256-channel instrument. The input sensitivity of the Model 2249A is 0.25 pC/count for a full- scale range of 256 pc. This is compatible with most available signal sources and no additional buffering or reshaping of any kind is required to digitize nanosecond pulses.
    The excellent long-term stability, temperature characteristics, and isolation between ADC channels assure accurate and reliable performance under the demanding conditions encountered in actual experiments. Confirmation of operation and calibration is provided by the unique test feature which allows all twelve ADC's or an entire system to simultaneously digitize a charge proportional to a dc level provided to a front-panel Lemo connector or patched into Pi, P2 or P5 of the Dataway connector.
    The Model 2249A offers excellent event rate capability through the incorporation of a fast clear and a fast digitizing rate. The fast clear input enables the ADC to begin digitizing on the command of a prompt gate and be reset, if necessary, before the end of conversion on the basis of delayed logic or chamber information.This feature eliminates the long input delay cables now required in these situations.
    End of conversion of modules which contain data is flagged by generation of a CAMAC LAM. Readout of modules which do not contain information can be eliminated either by use of the LAM signals or through Q suppression.
