The 10-Bit Voltage DAC Implemented in TSMC 90nm is a low sample rate Voltage DAC that is ideal for low frequency housekeeping applications. The Voltage DAC is implemented with as a current steering architecture and output buffer which implement I-V conversion to drive capacitive and resistive loads. The output is a single ended voltage with a 2.5V output swing.
The power of the Voltage DAC is determined by the noise requirements, the load, and the maximum sample rate. Trade offs can be made on the power consumption by limiting any of these specifications. TBDmW is quoted for the total power for 2MHz update frequency operation driving a 15pF and 5Kohm parallel load.
This 10-bit Voltage DAC features an excellent static performance that includes ±0.25LSB DNL and ±0.6LSB INL.
The 10-Bit Voltage DAC is ideal for integration with a DSP engine, and can be cost-effectively ported across foundries and process nodes upon request.
