The MAX1214N is a monolithic, 12-bit, 210Msps analog-to-digital converter (ADC) optimized for outstanding dynamic performance at high-IF frequencies beyond 300MHz. The product operates with conversion rates up to 210Msps while consuming only 799mW. At 210Msps and an input frequency up to 100MHz, the MAX1214N achieves an 81.3dBc spurious-free dynamic range (SFDR) with excellent 67dB 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. The MAX1214N 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 420MHz. 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 MAX1214N 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 the Pin-Compatible Versions table for a complete selection of 8-bit, 10-bit, and 12-bit high-speed ADCs in this family.
The MAX1214N is a monolithic 12‑bit analog‑to‑digital converter optimized for broadband applications. It delivers up to 210 Msps conversion rate while consuming only 799 mW from a single 1.8 V supply. The device features LVDS‑compatible digital outputs, an on‑chip selectable divide‑by‑2 clock, and a low‑noise 1.24 V band‑gap reference.
The converter is offered in a 68‑pin QFN‑EP package and operates over an industrial temperature range (‑40 °C to +85 °C). Detailed electrical characteristics include a 12‑bit resolution, 700 MHz full‑power analog bandwidth, and excellent dynamic performance with SNR up to 67 dB and SFDR up to 88.5 dBc.
