LTM2220-AA

OBSOLETE PRODUCT Data Sheet For Reference Only

The LTM2220-AA is a 170Msps sampling 12-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTM2220-AA is perfect for demanding communications applications with AC performance that includes 66.2dB SNR and 84dB spurious free dynamic range.

DC specs include ±0.5LSB INL (typ), ±0.3LSB DNL (typ) and no missing codes over temperature.

The CLK+ and CLK− inputs may be driven differentially or single ended with a sine wave, PECL, TTL or CMOS inputs. A clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.

The LTM2220-AA is pin compatible with the AD9430 when used with LVDS outputs, 2’s complement output format and the 1.536V_PP input range.
