GENERAL DESCRIPTION
The AD9040A is a complete 10-bit monolithic sampling analog-
to-digital converter (ADC) with on-board track-and-hold and
reference. The unit is designed for low cost, high performance
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
input requires a signal of 2 V p-p amplitude. The two-step
architecture used in the AD9040A is optimized to provide the
best dynamic performance available while maintaining low
power requirements of only 940 mW typically; maximum dissi-
pation is 1.1 watt at 40 MSPS.
The signal-to-noise ratio (SNR), including harmonics, is 53 dB,
or 8.5 ENOB, when sampling an analog input of 10.3 MHz at
40 MSPS. Competitive devices perform at less than 7.5 ENOB
and require external references and larger input signals.
The AD9040A A/D converter is available as either a 28-lead
plastic DIP or a 28-lead SOIC. 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.

PRODUCT HIGHLIGHTS
1. CMOS compatible logic for direct interface to ASICs.
2. On-board T/H provides excellent high frequency perfor-
mance on analog inputs, critical for communications and
medical imaging applications.
3. High input impedance and 2 volt p-p input range reduce
need for external amplifiers.
4. Easy to use; no cumbersome external voltage references
required, allowing denser packing of ADCs for multichannel
applications.
5. Available in 28-lead plastic DIP and SOIC packages.
6. Evaluation board includes AD9040AJR, reconstruction
DAC, and latches. Space is available near the analog input
and digital outputs of the converter for additional circuits.
Order as part number AD9040A/PCB (schematic shown in
data sheet).
