1.8V, Low-Power, 12-Bit, 250Msps

ADC for Broadband Applications

MAX215N

General Description

Features

ꢀ 250Msps Conversion Rate

The MAX1215N is a monolithic, 12-bit, 250Msps ana-

log-to-digital converter (ADC) optimized for outstanding

dynamic performance at high-IF frequencies beyond

300MHz. The product operates with conversion rates

up to 250Msps while consuming only 886mW.

ꢀ Excellent Low-Noise Characteristics

SNR = 66.7dB at f = 100MHz

SNR = 65.6dB at f = 250MHz

ꢀ Excellent Dynamic Range

At 250Msps and an input frequency of 100MHz, the

MAX1215N achieves an 84.7dBc spurious-free dynam-

ic range (SFDR) with e6.7dB signal-to-noise ratio (SNR)

that remains flat (within 2dB) for input tones up to

250MHz. This makes it ideal for wideband applications

such as communications receivers, cable-head end

receivers, and power-amplifier predistortion in cellular

base-station transceivers (BTS).

SFDR = 84.7dBc at f = 100MHz

SFDR = 80dBc at f = 250MHz

ꢀ Single 1.8V Supply

and f = 100MHz

ꢀ On-Chip Track-and-Hold Amplifier

ꢀ Internal 1.25V-Bandgap Reference

The MAX1215N operates from a single 1.8V power sup-

ply. The analog input is designed for AC-coupled differ-

ential or single-ended operation. The ADC also features a

selectable on-chip divide-by-2 clock circuit that accepts

clock frequencies as high as 500MHz. A low-voltage dif-

ferential signal (LVDS) sampling clock is recommended

for best performance. The converter provides LVDS-com-

patible digital outputs with data format selectable to be

either two’s complement or offset binary.
