MAXIM MAX5187 MAX5190 8-Bit, 40MHz, Current Voltage-Output DACs
Summary
Discover high-performance signal integrity with the MAX5187/MAX5190 DACs. These 8-bit, current/voltage output converters are ideal for demanding applications like arbitrary waveform generation and signal reconstruction. Designed for single-supply operation (+2.7V to +3.3V), they deliver low distortion and a wide spurious-free dynamic range (up to 70dB). The manual provides comprehensive details on performance metrics, advanced power-saving modes, and proper PCB design guidelines for optimal integration in your digital signal processing projects.

Frequently Asked Questions
What operational temperature range do the DACs support?
The MAX5187/MAX5190 are specified for the extended temperature range of -40°C to +85°C.
Can I run this device on a single supply voltage?
Yes, the devices operate from a single supply of +2.7V to +3.3V.
How do I ensure optimal signal integrity for high speeds?
Use a multilayer PCB with separate analog and digital ground planes, and decouple AV/DV pins using 10µF and 0.1µF capacitors.
What are the modes of operation for power saving?
The DACs offer three modes: normal use, low-power standby, and full shut-down (with a minimal shutdown current of 1µA max).
Which MAX series device offers voltage output capability?
The MAX5190 provides equal specifications to the MAX5187 but is explicitly mentioned for voltage output operation.
