Dual-Channel, 10-Bit, 100Msps ADC
MAX9516
General Description
Features
The MAX19516 dual-channel, analog-to-digital convert-
er (ADC) provides 10-bit resolution and a maximum
sample rate of 100Msps.
o Very-Low-Power Operation (57mW/Channel at
100Msps)
o 1.8V or 2.5V to 3.3V Analog Supply
The MAX19516 analog input accepts a wide 0.4V to
1.4V input common-mode voltage range, allowing DC-
coupled inputs for a wide range of RF, IF, and base-
band front-end components. The MAX19516 provides
excellent dynamic performance from baseband to high
input frequencies beyond 400MHz, making the device
ideal for zero-intermediate frequency (ZIF) and high-
intermediate frequency (IF) sampling applications. The
typical signal-to-noise ratio (SNR) performance is
60dBFS and typical spurious-free dynamic range
o Excellent Dynamic Performance
60dBFS SNR at 70MHz
82dBc SFDR at 70MHz
o User-Programmable Adjustments and Feature
Selection through an SPI™ Interface
o Selectable Data Bus (Dual CMOS or Single
Multiplexed CMOS)
o DCLK Output and Programmable Data Output
(SFDR) is 82dBc at f = 70MHz and f
= 100MHz.

Timing Simplifies High-Speed Digital Interface
The MAX19516 operates from a 1.8V supply.
Additionally, an integrated, self-sensing voltage regula-
tor allows operation from a 2.5V to 3.3V supply (AVDD).
The digital output drivers operate on an independent
supply voltage (OVDD) over the 1.8V to 3.5V range.
The analog power consumption is only 57mW per chan-
o Very Wide Input Common-Mode Voltage Range
(0.4V to 1.4V)
o Very High Analog Input Bandwidth (> 850MHz)
o Single-Ended or Differential Analog Inputs
o Single-Ended or Differential Clock Input
nel at V
= 1.8V. In addition to low operating
AVDD
power, the MAX19516 consumes only 1mW in power-
down mode and 17mW in standby mode.
o Divide-by-One (DIV1), Divide-by-Two (DIV2), and
Divide-by-Four (DIV4) Clock Modes
Various adjustments and feature selections are avail-
able through programmable registers that are
accessed through the 3-wire serial-port interface.
Alternatively, the serial-port interface can be disabled,
with the three pins available to select output mode,
data format, and clock-divider mode. Data outputs are
available through a dual parallel CMOS-compatible out-
put data bus that can also be configured as a single
multiplexed parallel CMOS bus.

The MAX19516 is available in a small 7mm x 7mm 48-
pin thin QFN package and is specified over the -40°C
to +85°C extended temperature range.
