Хотелось бы увидеть ТО на эту микросхему 1586ПА3БУ.

Выслал ТУ на ваш e-mail.

Было бы полезно, если бы вы указали, что конкретно вас в этой микросхеме интересует.

Спасибо за ТУ.
Больше всего моему начальству нравится отечественный производитель и параллельный интерфейс.

Что важнее в 2-х канальных ЦАП с параллельным интерфейсом?

Варианты:
1. маленький корпус, типа Н09.28-1В или 5123.28-1.01, но при этом побайтовая запись.
2. корпус побольше, типа Н16.48-2В или 5142.48-А, но при этом запись через чисто параллельную шину все 12 разрядов?

при наличии в линейке 2-х канальных 12р ЦАП с SPI в корпусе 5119.16-А.
и при наличии 1-канальных 12р. ЦАП в корпусе Н09.28-1В с чисто параллельной шиной.

Есть желающие высказаться?)

Здравствуйте.
При обсуждении такого вопроса считаю важным принять во внимание максимальную рабочую частоту ЦАП.
Если она не велика (до 1М), то приоритет, считаю, стоит отдать маленькому корпусу, если она велика (более 10М) - вероятно чисто параллельная шина приоритетнее.
