Dual-Channel, 10-Bit, 130Msps ADC
General Description
The MAX19517 dual-channel, analog-to-digital converter
(ADC) provides 10-bit resolution and a maximum sam-
ple rate of 130Msps.
The MAX19517 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 MAX19517 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
59.8dBFS and typical spurious-free dynamic range
(SFDR) is 82dBc at f_IN = 70MHz and f_CLK = 130MHz.
The MAX19517 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 74mW per chan-
nel at V_AVDD = 1.8V. In addition to low operating
power, the MAX19517 consumes only 1mW in power-
down mode and 21mW in standby mode.
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 MAX19517 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.
Refer to the MAX19505, MAX19506, and MAX19507
data sheets for pin- and feature-compatible 8-bit,
65Msps, 100Msps, and 130Msps versions, respectively.
Refer to the MAX19515 and MAX19516 data sheets for
pin- and feature-compatible 10-bit, 65Msps and
100Msps versions, respectively.
