When used with an op amp and a multiplexer, the ADSST-EM-2030 surpasses the accuracy requirement of the IEC1036 standard. ADSST-EM-2030 is a MicroConverter® consisting of a microcontroller, 6-channel, 12-bit ADC, SPI port, program memory and Flash for storage of constants. The only analog circuitry used in ADSST-EM-2030 is the ADC. All other signal processing is carried out in digital domain. This provides superior accuracy over extreme environmental conditions and time. ADSST-EM-2030 can drive an electromechanical counter or a 2-phase stepper motor counter, or can be interfaced to a microcontrolle...
