PRODUCT DESCRIPTION
The AD1380 is a complete, low cost 16-bit analog-to-digital
converter, including internal reference, clock and sample/hold
amplifier. Internal thin-film-on-silicon scaling resistors allow
analog input ranges of ± 2.5 V, ± 5 V, ± 10 V, 0 V to +5 V and
0 V to +10 V.
Important performance characteristics of the AD1380 include
maximum linearity error of ± 0.003% of FSR (AD1380KD) and
maximum 16-bit conversion time of 14 µs. Transfer characteris-
tics of the AD1380 (gain, offset and linearity) are specified for
the combined ADC/SHA, so total performance is guaranteed as
a system. The AD1380 provides data in parallel and serial form
with corresponding clock and status outputs. All digital inputs
and outputs are TTL or 5 V CMOS compatible.
