DAC0808 8-bit DAC Digital to Analog Converter IC

Features:

• 8 bit parallel digital data input.
• Fast settling time (typical value): 150 ns.
• Relative accuracy at 0.19% maximum error.
• Full-scale current match: 1 LSB.
• TTL and CMOS are compatible, Non-inverting digital inputs.
• High speed multiplying input slew rate: 8 mA/?s.

DAC0808 is a Digital to Analog converter IC used for converting 8-bit digital data input to analog signal output. It is a monolithic Integrated Circuit featuring a full-scale output current config time of 150 nanoseconds while dissipating only 33 mW with 5V supplies. This IC?s accuracy of conversion is good and power consumption is also low. The power supply currents of 0808DAC are independent of bit codes and exhibit constant device characteristics over the entire supply voltage range.

              0808DAC IC is used in devices where a digital to analog conversion is required. The chip used to be popular a decade ago and its applications used to be many but at present there are many modern IC that can perform DAC with higher resolution speed and efficiency. So this device is mainly used for reference and beginner applications and nothing more. For advanced applications microcontroller with DAC feature or DAC IC with the serial interface is preferred at present.
