DESCRIPTION
The HS 3120 is a precision monolithic 12-bit
multiplying DA C with internal two-stage input
storage registers for easy interfacing with
microprocessor busses. It is packaged in a 28-pin DIP
to give high I/O design flexibility.
DOUBLE BUFFERED - The input registers are sectioned
into 3 segments of 4 bits each, all individually
controls are level-triggered to allow static or dynamic
addressable. The DA C-register, following the input
operation.

M ICRO PROCESSOR COM PA TIBLE — The HS 3120 has
been designed for great flexibility in connecting to
bus-oriented systems. The 12 data inputs are
organized into 3 independent addressable 4-bit input
registers such that the HS 3120 can be connected to
either a 4, 8 or 16-bit data bus. The control logic of
the HS 3120 includes chip enable and latch enable
inputs for flexible memory mapping. All
internal. The resistor ladder network termination is
externally available, thus eliminating an external
resistor for the 1 LSB offset in bipolar mode.
M ONOLITHIC CM OS CONSTRUCTION - The HS 3120 is
a one-chip CM OS circuit with a resistor ladder
network designed for 0.01% linearity without laser
trimming. Small chip size and high manufacturing
yields result in greatly reduced cost.
