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.
