HI5767/21A

Encoders, Decoders, Converters Overview

The HI5767/21A is a monolithic, 10-bit analog-to-digital converter (ADC) designed for high-speed applications requiring wide bandwidth and low power consumption. It features a fully differential pipelined architecture with an internal sample-and-hold circuit, enabling operation at speeds up to 60 MSPS. The device consumes approximately 260mW of power at maximum sampling rates. Data output latches are integrated to present valid data to the output bus with a latency of seven clock cycles. It supports both fully differential and single-ended analog inputs and is pin-for-pin functionally compatible with the HI5702, HI5703, and HI5746.

Encoders, Decoders, Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the PDSO-28 specification. Ensure compliance with RoHS directives if required by the end application, noting that specific suffixes may indicate lead-free variants. Validate electrical parameters against the official datasheet before integration into production designs.

Encoders, Decoders, Converters Selection Notes

Select this component when a 10-bit resolution and 60 MSPS sampling rate are required in a CMOS process. Consider its low power consumption of 260mW for battery-operated or thermally constrained environments. Verify compatibility with existing system clocks due to the fixed seven-cycle latency. Ensure the analog input range matches the system requirements, as the device accepts differential or single-ended signals within specified limits.

Encoders, Decoders, Converters Part Context

The HI5767 series belongs to Harris Corporation's family of high-speed analog-to-digital converters. These devices were engineered to address the growing demand for efficient data conversion in portable and high-performance electronic systems. The HI5767 specifically serves as a voltage reference companion to the HI5766 ADC, though they share architectural similarities and target overlapping application domains requiring precise signal digitization.

Encoders, Decoders, Converters Replacement Considerations

The HI5767/21A is pin-for-pin functionally compatible with the HI5702, HI5703, and HI5746. Designers can substitute these parts directly without modifying the PCB layout, provided that electrical specifications such as input range and power consumption meet the system requirements.
