PNA7509 Datasheet 7-bit A/d Conveter

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: DEVELOPMENT DATA This data sheet contains advance information and specifications are subject to change without notice.

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 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.

Key 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.
