Description

The AD6140 is a bandpass SD ADC IF IC for receivers requiring a high dynamic range and multiple filter bandwidths. With an external decimation filter, it creates a multibit analog-to-digital converter. The AD6140 consists of a variable gain, low noise preamplifier, mixer, AGC detector, bandpass SD modulator, an ECL-to-CMOS level translator for the system clock, and an auxiliary amplifier for use in biasing a discrete LNA. It is designed to operate with Motorola's ReFLEX chipset solution. Contact Motorola directly for more information about the ReFLEX chipset solution. With data and clock outputs at CMOS logic levels, it interfaces to an external decimation filter. It comes in a 20-lead plastic SSOP and operates over the 40°C to +85°C industrial temperature range at 2.7 V.
