PNA7509 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 prises 129 parators, a reference resistor chain, bining logic, transcoder stages, and TTL output buffers which are positive edge triggered and can be switched into 3-state mode.
PNA7509 Key Features
- 7-bit resol ution
- No external sample and hold required
- High input impedance
- Binary or two's plement 3-state TTL outputs
- Overflow and underflow 3-state TTL outputs
