FEATURES…

TheHS7541Aisalow–cost,highstabilitymono-

lithic 12–bit CMOS 4–quadrant multiplying

DAC. It is constructed using a proprietary low–

TCR thin–film process that requires no laser–

trimming to achieve 12–bit performance. With

its inherent high stability and a segmented (de-

coded) DAC architecture, the HS7541A retains

its performance over time and temperature. To

further improve reliability, all digital inputs are

protected against 2KV ESD. Each DAC is fully

characterized by all–codes testing to eliminate

any hidden errors.

Pin 15 — D₀(LSB) — Data Bit 0 (Least Significant

Bit).

The HS7541A consists of a highly stable thin–

film R–2R ladder network and twelve NMOS

current switches (please refer to the Block Dia-

gram on the first page of this data sheet). The

switchesaretemperaturecompensated,andtheir

“on” resistances are binarily scaled so that the

voltage drop across each switch is identical,

which contributes to the stability of the DAC.

The internal feedback resistor used in the output

current–to–voltage conversion by an external

op amp is matched to the R–2R ladder.

Pin 16 — V_DD— +5V to +15V Power Supply.

Pin 17 — V_REF— Voltage Reference Input.

Pin 18 — R_FB— Feedback Resistor.

Pin 1 — I_O1— Inverted Current Output.

Pin 2 — I_O2— Current Output.

Pin 3 — GND — Analog Ground.

Pin 4 — N.C. — No Connection.

Pin 5 — D₁₁(MSB) — Data Bit 11 (Most

Significant Bit).

The HS7541A is a 12-bit multiplying D/A con-

verter consisting of a highly stable, SiChrome

thin-film R-2R resistor ladder network, and

twelvepairsofNMOScurrent-steeringswitches

on a monolithic chip.

Asimplifiedcircuit oftheHS7541A isshownin

Figure 1. The R-2R inverted ladder binarily

divides the input currents that are switched

between the I_OUT1and I_OUT2bus lines. This switch-

ing allows a constant current to be maintained in

each ladder leg independent of the input code.
