GENERAL DESCRIPTION
The AD9040A is a complete 10-bit monolithic sampling analog-
to-digital converter (ADC) with on-board track-and-hold (T/H)
and reference. The unit is designed for low cost, high perfor-
mance applications and requires only an encode signal to achieve
40 MSPS sample rates with 10-bit resolution.
Digital inputs and outputs are CMOS compatible; the analog
PRODUCT HIGHLIGHTS
1. CMOS compatible logic for direct interface to ASICs.
2. On-board track-and-hold provides excellent high frequency
performance on analog inputs, critical for communications
and medical imaging applications.
3. High input impedance and 2 V p-p input range reduce need
for external amplifiers.

and require external references and larger input signals.
The AD9040A A/D converter is available in either a 28-lead
PDIP or a 28-lead SOIC package. The two models operate over
a commercial temperature range of 0°C to 70°C. Contact the
factory regarding availability of ceramic military temperature
range devices.
