ZHCS065G March 2011 – January 2024 DAC3482
PRODUCTION DATA
The DAC3482 has a parity check test that enables continuous validity monitoring of the data received by the DAC. Parity check testing in combination with the data pattern checker offer an excellent solution for detecting board assembly issues due to missing pad connections.
For the parity check test, an extra parity bit is added to the data bits to make sure the total number of set bits (bits with logic value of 1b) is even or odd. This simple scheme is used to detect data transfer errors. Parity testing is implemented in the DAC3482 in two ways: word-by-word parity and block parity.
