<strong>MicroMCA527</strong><br />
Ultra miniature Multi Channel Analyzer Module<br />
The <strong>MicroMCA527</strong> is an OEM MCA designed for minimum size, minimum power<br />
requirements and to be integrated within any spectroscopical gamma detector. Software and<br />
firmware are mostly compatible to MCA527, MCA527L and MCA527 OEM. Power supply<br />
supply and communication is by a MicroUSB connector. The ADC inputs are directly<br />
connected to the input pins, where a custom preamplifier as driver is expected.<br />
µMCA527from top side and back side, on the right the micro USB connector<br />
Different interface (I²C and RS232) and power supply lines (1.5V (ADC ref.), 1.8V, 3.3V, 5V<br />
(from USB)) makes it possible to develop additional functions, like GPS receivers, sensors or<br />
microcontrollers, around the module. Please contact us if you need support or a firmware<br />
extension. Already available add-ons are PMT-compatible preamplifier, HV up to +/-1000V<br />
and a PMT (14 pin) socket with all this included.<br />
Technical Data<br />
Amplifier<br />
Differential input directly to ADC with common<br />
mode at 1.5V and a range of +/-1V. May also<br />
be used single ended with the negative input<br />
fixed at 1.5V. Will accept positive as well as<br />
negative signals. Low pass filtering of the input<br />
signal with around 3 MHz bandwidth is<br />
recommended.<br />
Linearity better than 0.1%.<br />
ADC<br />
14bit, 10 MSps<br />
Integral Nonlinearity
power supply:<br />
USB, 4.5 V ... 5.25 V, 50mA in idle mode,<br />
80mA max at full operation. With external<br />
consumers connected, supply current may<br />
increase up to 500mA.<br />
Computer Interface<br />
USB. Other possibilities see variants.<br />
Firmware, Software<br />
All firmware commands analog to MCA166 and<br />
MCA527 with some extensions. Will operate<br />
with some MCA166/MCA527 software.<br />
Documentation will include description of all<br />
firmware commands and a small programming<br />
guide with examples.<br />
Mechanical<br />
Circuit board 50 mm x 20 mm*5mm.<br />

Mechanical dimensions: 21*35*50mm (height * with *<br />
length)<br />
HV up to +/-1000V, 0.5mA max., programmable (select<br />
polarity with ordering).<br />
For positive voltage PMT, AC coupled output, an<br />
external HV proof coupling capacitor of around 2-4nF is<br />
necessary.<br />
Charge measurement up to 160 pC / 800 pC in two<br />
settable ranges.<br />
Depending on HV setting and loading, the current<br />
consumption may increase up to 260mA at 5V.<br />
µMCA527 base<br />
Includes µMCA527 with preamplifier, HV and voltage<br />
divider.<br />
Maximum diameter 65mm, at the end 59mm, overall<br />
length 111mm.<br />
suitable for PMT type R6231(-100), R6233 or similar. On<br />
request available also with pinning compatible to R1306,<br />
R1307.<br />
maximum diameter of PMT at socket allowed: 59mm.<br />
µMCA Ethernet/RS232<br />
External communication by Ethernet (powered by Power<br />
over Ethernet, PoE; or communication by RS232<br />
(external power supply required) instead of USB.<br />
