General Description
The MAX19505 dual-channel, analog-to-digital convert-
er (ADC) provides 8-bit resolution and a maximum sam-
ple rate of 65Msps.
The MAX19505 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 MAX19505 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
49.8dBFS and typical spurious-free dynamic range
(SFDR) is 69dBc at fIN = 70MHz and fCLK = 65MHz.
The MAX19505 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 43mW per chan-
nel at VAVDD = 1.8V. In addition to low operating
power, the MAX19505 consumes only 1mW in power-
down mode and 15mW 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 MAX19505 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 MAX19515, MAX19516, and MAX19517
data sheets for pin- and feature-compatible 10-bit,
65Msps, 100Msps, and 130Msps versions, respectively.
Refer to the MAX19506 and MAX19507 data sheets for
pin- and feature-compatible 8-bit, 100Msps and
130Msps versions, respectively.
