GENERAL D ESCRIP TIO N

T he AD7537 contains two 12-bit current output DACs on one

monolithic chip. A separate reference input is provided for each

DAC. T he dual DAC saves valuable board space, and the

monolithic construction ensures excellent thermal tracking.

Both DACs are guaranteed 12-bit monotonic over the full tem-

perature range.

T he AD7537 has a 2-byte (8 LSBs, 4 MSBs) loading structure.

It is designed for right-justified data format. T he control signals

for register loading are A0, A1, CS, WR and UPD. Data is

loaded to the input registers when CS and WR are low. T o

transfer this data to the DAC registers, UPD must be taken low

with WR.

1. DAC to DAC Matching:

Since both DACs are fabricated on the same chip, precise

matching and tracking is inherent. Many applications which

are not practical using two discrete DACs are now possible.

T ypical matching: 0.5%.

Added features on the AD7537 include an asynchronous CLR

line which is very useful in calibration routines. When this is

taken low, all registers are cleared. T he double buffering of the

data inputs allows simultaneous update of both DACs. Also,

each DAC has a separate AGND line. T his increases the device

versatility; for instance one DAC may be operated with

AGND biased while the other is connected in the standard

configuration.

2. Small Package Size:

T he AD7537 is packaged in small 24-pin 0.3" DIPs and in

28-terminal surface mount packages.

3. Wide Power Supply T olerance:

T he device operates on a +12 V to +15 V V_DD, with ±10%

tolerance on this nominal figure. All specifications are

guaranteed over this range.

T he AD7537 is manufactured using the Linear Compatible

CMOS (LC²MOS) process. It is speed compatible with most

microprocessors and accepts T T L, 74HC and 5 V CMOS logic

level inputs.
