PRODUCT DESCRIPTION
The AD9214 is a 10-bit monolithic sampling analog-to-digital
converter (ADC) with an on-chip track-and-hold circuit, and
is optimized for low cost, low power, small size, and ease of use.
The product operates up to 105 MSPS conversion rate with
outstanding dynamic performance over its full operating range.
The ADC requires only a single 3.3 V (2.7 V to 3.6 V) power
supply and an encode clock for full performance operation. No
external reference or driver components are required for many
applications. The digital outputs are TTL/CMOS compatible
and a separate output power supply pin supports interfacing
with 3.3 V or 2.5 V logic.
The clock input is TTL/CMOS compatible. In the power-down
state, the power is reduced to 30 mW. A gain option allows
support for either 1 V p-p or 2 V p-p analog signal input swing.
Fabricated on an advanced CMOS process, the AD9214 is
available in a 28-lead surface-mount plastic package (28-SSOP)
specified over the industrial temperature range (–40°C to +85°C).
PRODUCT HIGHLIGHTS
High Performance—Outstanding ac performance from 65 MSPS
to 105 MSPS. SNR greater than 55 dB typical and as high
as 58 dB.
Low Power—The AD9214 at 285 mW consumes a fraction of
the power available in existing high-speed monolithic solutions.
In sleep mode, power is reduced to 30 mW.
Single Supply—The AD9214 uses a single 3 V supply, simplify-
ing system power supply design. It also features a separate digital
output driver supply line to accommodate 2.5 V logic families.
Small Package—The AD9214 is packaged in a small 28-lead
surface-mount plastic package (28-SSOP).

*tV and tPD are measured from the 1.5 V level of the ENCODE input to the 50% levels of the digital output swing. The digital output load during test is not to exceed
an ac load of 5 pF or a dc current of ± 40 µA.
