Description
The MAX1215N is a monolithic, 12-bit, 250Msps analog-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.

At 250Msps and an input frequency of 100MHz, the MAX1215N achieves an 84.7dBc spurious-free dynamic range (SFDR) with excellent 66.7dB 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).

The MAX1215N operates from a single 1.8V power supply. The analog input is designed for AC-coupled differential 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 differential signal (LVDS) sampling clock is recommended for best performance. The converter provides LVDS-compatible digital outputs with data format selectable to be either two's complement or offset binary.

The MAX1215N is available in a 68-pin QFN package with exposed paddle (EP) and is specified over the industrial (-40°C to +85°C) temperature range.

See a parametric table of the complete family of pin-compatible, 8-/10-/12-bit high-speed ADCs.
