DAC0808LCN 8-Bit D/A Converter ±4.5V to ±18V 2mA DIP-16
The DAC0808LCN is an 8-bit monolithic digital-to-analog converter (DAC) designed for high-speed digital-to-analog conversion. It provides a typical full-scale output current settling time of 150 ns while dissipating only 33 mW with ±5V supplies.
The DAC0808 provides relative accuracy better than ±0.19%, supporting 8-bit monotonicity and linearity. Its zero-level output current is less than 4 µA, providing 8-bit zero accuracy for a reference current of IREF ≥ 2 mA.
The device interfaces directly with TTL, DTL, and CMOS logic levels and is specified for a power supply voltage range of ±4.5V to ±18V. The DAC0808LCN is supplied in the N16A 16-pin Dual-In-Line Package and has an operating temperature range of 0°C to +75°C.
