BW1254X
GENERAL DESCRIPTION
bw1254x is a CMOS 14bit analog-to-digital converter (ADC). It converts the analog input signal into 14bit binary digital codes at a maximum sampling rate of 10MHz. The device is a monolithic ADC with an on-chip, high-performance, sample-and-hold Amplifier (SHA) and current reference and voltage reference. The structure allows both differential and single-ended input.
