AD9705BCPZ — это 10-разрядный токовый ЦАП серии TxDAC для передающих трактов.
Он обеспечивает максимальную частоту обновления 175 MSPS при питании до 3.6 V.
Микросхема оптимизирована для малой мощности при сохранении высокого динамического качества сигнала.
Встроенный опорный источник 1.0 V и регулируемый выходной ток упрощают согласование с внешними цепями.
Диапазон питающих напряжений и режимов пониженного потребления позволяет использовать ЦАП в портативных и энергосберегающих системах.
