CA3304AE

Analog To Digital Converters (ADC) Overview

The Harris Corporation CA3304AE is a CMOS parallel flash analog-to-digital converter designed for high-speed digitization with low power consumption. It operates on a single power supply ranging from 3V to 7.5V and achieves a sampling rate of 25 MSPS, corresponding to a 40ns conversion time at a 5V supply. The device features 4-bit latched three-state outputs with overflow and data change indicators. It exhibits inherent resistance to latch-up due to its SOS process technology and offers a typical input bandwidth of 25MHz.

Analog To Digital Converters (ADC) Part Context

The CA3304 series was originally developed by Harris Semiconductor and later integrated into Intersil and subsequently Renesas Electronics product portfolios. The CA3304AE represents the commercial grade variant within this family of 4-bit flash ADCs, sharing architectural similarities with higher-resolution counterparts like the CA3306.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may include the Intersil HI3304 or Fairchild TDC1044A. Verification of electrical parameters such as nonlinearity specifications and output logic levels is required when substituting these components.
