Bandpass ⌺⌬ IF Subsystem

AD6140

FEATURES

IF Subsystem

GENERAL DESCRIPTION

The AD6140 is a bandpass Σ∆ 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 Σ∆ modulator, an

ECL-to-CMOS level translator for the system clock, and an

auxiliary amplifier for use in biasing a discrete LNA. It is de-

signed 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.
