GENERAL DESCRIPTION
The AD7943, AD7945 and AD7948 are fast 12-bit multiplying
DACs that operate from a single +5 V supply (Normal Mode)
and a single +3.3 V to +5 V supply (Biased Mode). The
AD7943 has a serial interface, the AD7945 has a 12-bit parallel
interface, and the AD7948 has an 8-bit byte interface. They will
replace the industry-standard AD7543, AD7545 and AD7548
in many applications, and they offer superior speed and power
consumption performance.
The AD7943 is available in 16-lead DIP, 16-lead SOP (Small
Outline Package) and 20-lead SSOP (Shrink Small Outline
Package).
The AD7945 is available in 20-lead DIP, 20-lead SOP and 20-
lead SSOP.
The AD7948 is available in 20-lead DIP, 20-lead SOP and 20-
lead SSOP.
