Overview
ZN427E8 / ZN427J8 MICROPROCESSOR COMPATIBLE 8-BIT SUCCESSIVE APPROXIMATION A-D CONVERTER The ZN427 is an 8-bit successive approximation converter with three-state outputs to permit easy interfacing to a common data bus.
The IC contains a voltage switching DAC, a fast comparator, successive approximation logic and a 2.
56V precision bandgap reference, the use of which is pin optional to retain flexibility.
An external fixed or varying reference may therefore be substituted, thus allowing ratiometic operation Only passive external components are required for operation of the converter.
FEATURES s Easy Interfacing to Microprocessor, or Operates as a 'Stand-Alone' Converter s Fast: 10 microseconds Conversion time Guaranteed s No Missing Codes over Operating Temperature Range s Data Outputs Three-State TTL Compatible, other Logic Inputs and Output TTL and CMOS Compatible s Choice of On-Chip or External Reference Voltage s Ratiometric Operation s Unipolar or Bipolar Input Ranges s Complement...
