Аналого-цифровые преобразователи (АЦП) AD7795BRUZ

АЦП , 16 бит, 470 выборок/с, Дифференциальный, Последовательный, Однополярный, 2.7 В

The AD7795BRUZ is a 6-channel 16-bit Low Power Sigma-Delta (Σ-Δ) ADC on-chip in-amp and reference for high precision measurement applications. It contains a low noise 16-bit Σ-Δ ADC with six differential inputs. The on-chip low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC. The complete analogue front ends device contains a precision low noise low drift internal band gap reference and can also accept up to two external differential references. Other on-chip features include programmable excitation current sources, burnout currents and a bias voltage generator that is used to set the common-mode voltage of a channel to AVDD/2. The low-side power switch can be used to power down bridge sensors between conversions minimizing the system's power consumption. ADC can be operated with either the internal clock or an external clock.
