NTE2053 Integrated Circuit 8–Bit MPU Compatible A/D Converter
Description: The NTE2053 is a
CMOS 8–bit successive approximation Analog to Digital converter in a 20–Lead DIP type package which uses a differential potentiometric ladder – similar to the 256R products. This device is designed to allow operation with the NSC800 and INS8080A derivative control bus, and TRI–STATER output latches directly drive the data bus. These A/Ds appear like memory locations or I/O ports to the microprocessor and no interfacing logic is needed. A new differential analog
voltage input allows increasing the common–mode rejection and offsetting the analog zero input
voltage value. In addition, the
voltage reference input can be adjusted to allow encoding any similar analog
voltage span to the full 8 bits of resolution. Features: D Compatible With 8080 MPU Derivatives – No Interfacing Logic Needed – Access Time: 135ns D Easy Interface to all Microprocessors, or Operates “Stand Alone” D Differential Analog
Voltage Inputs D Logic Inputs and Outputs Meet Both MOS and TTL
Voltage Level Specifications D Works With 2.5V (NTE952)
Voltage Reference D On–Chip Clock Generator D 0V to 5V Analog Input
Voltage Range with Single 5V Supply D No Zero Adjust Required D Operates Ratiometrically or with 5V, 2.5V, or Analog Span Adjusts
