GENERAL DESCRIPTION
The AD9460 is a 16-bit, monolithic, sampling, analog-to-digital
converter (ADC) with an on-chip track-and-hold circuit. It is
optimized for performance, small size, and ease of use. The
AD9460 operates up to 105 MSPS, providing a superior signal-
to-noise ratio (SNR) for instrumentation, medical imaging, and
radar receivers using baseband (<100 MHz) and IF frequencies.
The ADC requires 3.3 V and 5.0 V power supplies and a low
voltage differential input clock for full performance operation.
No external reference or driver components are required for
many applications. Data outputs are CMOS or LVDS compatible
(ANSI-644 compatible) and include the means to reduce the
overall current needed for short trace distances.

Optional features allow users to implement various selectable
operating conditions, including input range, data format select,
and output data mode.
The AD9460 is available in a Pb-free, 100-lead, surface-mount,
plastic package (TQFP_EP) specified over the industrial tem-
perature range of −40°C to +85°C.
PRODUCT HIGHLIGHTS
1. True 16-bit linearity.
2. High performance: outstanding SNR performance for
baseband IFs in data acquisition, instrumentation,
magnetic resonance imaging, and radar receivers.
3. Ease of use: on-chip reference and high input impedance,
track-and-hold with adjustable analog input range, and an
output clock simplifies data capture.
4. Packaged in a Pb-free, 100-lead TQFP/EP.
5. Clock duty cycle stabilizer (DCS) maintains overall ADC
performance over a wide range of clock pulse widths.
6. Out-of-range (OR) outputs indicate when the signal is
beyond the selected input range.

approximately 5 pF loading on each output bit for CMOS output mode.
2 Input capacitance or resistance refers to the effective impedance between one differential input pin and AGND. Refer to Figure 6 for the equivalent analog input structure.
3 For SFDR = AVDD1, IAVDD2 power increases by ~70 mW for the AD9460BSVZ-80 and ~20 mW for the AD9460BSVZ-105.
