HI5805 Functional Diagram
Description
Support is limited to customers who have already adopted these products.
The HI5805 is a monolithic, 12-bit, Analog-to-Digital Converter fabricated in Intersil's HBC10 BiCMOS process. It is designed for high speed, high resolution applications where wide bandwidth and low power consumption are essential. The HI5805 is designed in a fully differential pipelined architecture with a front end differential-in-differential-out sample-and-hold (S/H). The HI5805 has excellent dynamic performance while consuming 300mW power at 5MSPS. The 100MHz full power input bandwidth is ideal for communication systems and document scanner applications. Data output latches are provided which present valid data to the output bus with a latency of 3 clock cycles. The digital outputs have a separate supply pin which can be powered from a 3. 0V to 5. 0V supply.

- Application NotePDF 503 KB an9675 Aug 13, 1999AI-generated Summary: Effective Number of Bits (ENOB) depends critically on precise coherence in A/D sampling, with small frequency shifts significantly impacting accuracy. Unwrapping reconstructs coherently sampled sine waves, while windowing controls spectral leakage by shaping the acquisition window. Resampling and interpolation adjust sample sets to avoid leakage in FFT analysis. Different window functions balance side lobe levels and bandwidth, affecting spectral resolution and leakage reduction.
- Application NotePDF 1.08 MB an002 Nov 19, 1998AI-generated Summary: Data acquisition and conversion involve quantization, where the smallest resolvable analog difference (quantum) depends on the full scale range and resolution. Quantization introduces an irreducible error called quantizing error or noise. Aperture time, the conversion time uncertainty, causes amplitude errors when signals change during conversion. Sample-hold circuits reduce aperture time by storing sampled signals. The Sampling Theorem states that sampling frequency must be at least twice the highest signal frequency to avoid distortion from frequency folding or aliasing. Natural binary code is commonly used for digital representation in converters, with the most and least significant bits defining the code's resolution and value.
- Application NotePDF 508 KB an9510 Aug 19, 1998AI-generated Summary: The document explains fundamental analog circuit concepts for digital designers, focusing on superposition, Thevenin equivalent circuits, and feedback principles. It details the operation and assumptions of inverting and non-inverting op amps, differential amplifiers, and the use of T networks in feedback paths. The text highlights the importance of feedback in controlling closed-loop gain and stability, and distinguishes between voltage and current feedback op amps, especially in high-frequency applications like video amplifiers.
- Application NotePDF 287 KB an9705 Feb 21, 1997AI-generated Summary: Coherent sampling requires the ratio of signal frequency to sampling frequency to be a rational number, expressed as ko/N. When this condition is not met, frequency smearing occurs across bins. Data Acquisition Systems (DAS) can mitigate this by windowing, fixing sampling frequency and tuning input frequency, or fixing input frequency and tuning sampling frequency. The latter two methods are practical for most systems. Pseudo-code illustrates the frequency response for non-integer ko values.
