Аналого-цифровые преобразователи (АЦП) MAX1184ECM+D

АЦП , низкой мощности, 10 бит, 20 Мвыборок/с, Дифференциальный, Параллельный, Однополярный, 2.7 В

The MAX1184ECM+D is a dual 10bit, 20Msps, 3V, low power ADC with internal reference and parallel outputs in 48 pin TQFP package. It features fully-differential wideband track and hold (T/H) inputs, driving two pipelined, 9-stage ADCs. The T/H driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters may also be operated with single ended inputs. In addition to low operating power, the MAX1184 features a 2.8mA sleep mode as well as a 1µA power-down mode to conserve power during idle periods. An internal 2.048V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of the internal or an externally derived reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1184 features parallel, CMOS-compatible three-state outputs. The digital output format is set to two's complement or straight offset binary through a single control pin.
