The AD9058 combines two independent, high performance,
8-bit analog-to-digital converters (ADCs) on a single monolithic
IC. Combined with an optional on-board voltage reference,
the AD9058 provides a cost-effective alternative for systems
requiring two or more ADCs.
Dynamic performance (SNR, ENOB) is optimized to provide
up to 50 MSPS conversion rates. The unique architecture
results in low input capacitance while maintaining high per-
formance and low power (<0.5 W/channel). Digital inputs
and outputs are TTL compatible.
Performance has been optimized for an analog input of 2 V p-p
(± 1 V; 0 V to 2 V). Using the on-board 2 V voltage reference,
the AD9058 can be set up for unipolar positive operation
(0 V to 2 V). This internal voltage reference can drive
Commercial (0°C to 70°C) and military (–55°C to +125°C)
temperature range parts are available. Parts are supplied in
hermetic 48-lead DIP and 44-lead “J” lead packages.
