Product specification
6-Bit A/D converter (parallel outputs)
NE5037
DESCRIPTION
The NE5037 is a low cost, complete successive-approximation
analog-to-digital (A/D) converter, fabricated using Bipolar/I
2
L
technology. With an external reference voltage, the NE5037 will
accept input voltages between 0V and V
REF
. An external START
pulse of at least 300ns in duration will provide the 6-bit result of the
conversion in parallel format. Full conversion with no missing codes
occurs in 9碌s.
