The AD7545 is a monolithic 12-bit CMOS multiplying DAC with onboard data latches. It is loaded by a single 12-bit wide word and directly interfaces to most 12- and 16-bit bus systems.
The AD7545 is a monolithic 12‑bit CMOS multiplying DAC designed for single‑supply operation from +5 V to +15 V. It features low gain temperature coefficient, fast TTL‑compatible data latches, and small 20‑lead DIP or surface‑mount packages.
The document includes detailed specifications (resolution, gain error, temperature coefficients, power dissipation), absolute maximum ratings, timing diagrams, circuit information for both analog and digital sections, basic application circuits, single‑supply operation guidelines, and microprocessor interfacing examples.
| Resolution | 12 bits |
|---|---|
| Supply Voltage Range | +5 V to +15 V |
| Gain Temperature Coefficient (typical) | 2 ppm/°C |
| Input High Voltage (TTL compatible, Vpp = +5 V) | 2.4 V min |
The AD7545 can operate from a single supply voltage of +5 V up to +15 V.
The typical gain temperature coefficient is 2 ppm/°C.
The AD7545 provides a 12‑bit resolution.
