15-Bit, 65Msps ADC with -79.3dBFS
Noise Floor for Baseband Applications
General Description
Features
The MAX1419 is a 5V, high-speed, high-performance
analog-to-digital converter (ADC) featuring a fully differ-
ential wideband track-and-hold (T/H) and a 15-bit con-
verter core. The MAX1419 is optimized for multichannel,
multimode receivers, which require the ADC to meet very
stringent dynamic performance requirements. With a
noise floor of -79.3dBFS, the MAX1427 allows for the
design of receivers with superior sensitivity.
ꢀ 65Msps Minimum Sampling Rate
ꢀ -79.3dBFS Noise Floor
ꢀ Excellent Dynamic Performance
76.2dB SNR at fIN=15MHz and AIN = -1dBFS
93.1dBc/95.5dBc Single-Tone SFDR1/SFDR2 at
fIN = 15MHz and AIN = -1dBFS
-91dBc Multitone SFDR at fIN1 = 10MHz
and fIN2 = 15MHz
The MAX1419 achieves two-tone, spurious-free dynamic
range (SFDR) of -91dBc for input tones of 10MHz and
15MHz. Its excellent signal-to-noise ratio (SNR) of 76.2dB
and single-tone SFDR performance (SFDR1/SFDR2) of
93.1dBc/95.5dBc at f = 15MHz and a sampling rate of
IN
65Msps make this part ideal for high-performance digital
receivers.
ꢀ Less than 0.25ps Sampling Jitter
ꢀ Fully Differential Analog Input Voltage Range of
2.56VP-P
ꢀ CMOS-Compatible Two’s-Complement Data Output
ꢀ Separate Data Valid Clock and Overrange Outputs
ꢀ Flexible-Input Clock Buffer
The MAX1419 operates from an analog 5V and a digital
3V supply, features a 2.56V
full-scale input range,
P-P
and allows for a sampling speed of up to 65Msps. The
input T/H operates with a -1dB full-power bandwidth of
200MHz.
ꢀ EV Kit Available for the MAX1419
(Order MAX1427EVKIT)
The MAX1419 features parallel, CMOS-compatible out-
puts in two’s-complement format. To enable the interface
with a wide range of logic devices, this ADC provides a
separate output driver power-supply range of 2.3V to
3.5V. The MAX1419 is manufactured in an 8mm x 8mm,
56-pin QFN package with exposed paddle (EP) for low
thermal resistance, and is specified for the extended
industrial (-40°C to +85°C) temperature range.
