sigma-delta analog-to-digital converter [¦sig·mə ¦del·tə ‚an·ə‚läg tü ‚dij·əd·əl kən‚vərd·ər]
(electronics) A converter that uses an analog circuit to generate a single-valued pulse stream in which the frequency of pulses is determined by the analog source, and then uses a digital circuit to repeatedly sum the number of these pulses over a fixed time interval, converting the pulses to numeric values.

No references found | ADI's AD7190 24-bit sigma-delta analog-to-digital converter delivers 7 nV noise and greater than 16-bits noise-free resolution up to 2. The ADuC706x family expands ADI's precision analog microcontroller portfolio by incorporating two 24-bit sigma-delta analog-to-digital converters (ADCs) and a host of analog peripherals with a 32-bit ARM7[TM] core to create a solution for precision sensing applications. The CDC products leverage ADI's expertise in high-precision sigma-delta technology and system integration by combining 24-bit resolution, low noise of 5 aF (10-18) per root hertz, and low power (1 mA max) with a complete range of on-chip analog functions, including a high-performance, 24-bit, sigma-delta analog-to-digital converter (ADC), a precision low-noise, low-drift voltage reference and a temperature sensor. |
