DESCRIPTION 

The demo board for the TSM1285 is a completely 
assembled and tested circuit board that can be used 
for evaluating the TSM1285. For easy and quick 
evaluation of the TSM1285, a Nano River Tech 
ViperBoard with an onboard microcontroller and 
FPGA for signal processing is available. The 
ViperBoard interfaces to any computer via USB port 
and a user-friendly Windows OS compatible software 
is available for evaluation. 
 
The TSM1285 – a single-supply, single-channel, 12-
bit analog-to-digital converter (ADC) - is an alternate 
source for the MAX1285 and a higher-speed upgrade 
to the MAX1240 and MAX1240 ADCs. The TSM1285 
combines a high-bandwidth track-and-hold (T/H), a 
high-speed serial digital interface, an in2.5V 
reference, and low conversion-mode power 
consumption. The TSM1285 operates from a single 
+2.7V to+3.6V supply and draws less than 2.5mA at 
300ksps.
