7-81T ANALOGUE-TO-DIGITAL CONVERTER (ADC 7)
GENERAL DESCRIPTION
The PNA7509 is a monolithic NMOS 7-bit analogue-to-digital converter (AOC) designed for video
applications. The device converts the analogue input signal into 7 -bit binary coded digital words at a
sampling rate of 22 MHz.
The circuit comprises 129 comparators, a reference resistor chain, combining logic, transcoder stages,
and TTL output buffers which are positive edge triggered and can be switched into 3-state mode. The
digital output is selectable in two's complement or binary coding.
The use of separate outputs for overflow and underflow detection facilitates full-scale driving.
Features
• 7-bit resol ution
• No external sample and hold required
• High input impedance
• Binary or two's complement 3-state TTL outputs
• Overflow and underflow 3-state TTL outputs
• All outputs positive-edge triggered
• Standard 24-pin package
Applications
• High-speed AID conversion
• Video signal digitizing
• Radar pulse analysis
• Transient signal analysis
• High energy physics research
