Working Principle

The working principle of the LTC2635HMSE-LMX8#PBF is based on the fact that each of its eight 8-bit DACs is loaded with a value determined by the binary inputs. When a logic level is applied to each of the eight DAC bits, a corresponding digital-to-analog coordinate is generated in the voltage output range. The voltage output range is programmable between 0 V and VREF, with the reference voltage being established by either the internal VREF or an external source through an external input pin.

The device also contains an on-chip low-noise voltage reference, an 8-bit resistor string, and a buffered voltage output. The on-chip voltage reference and high accuracy of the DAC string ensures precise and linear output voltages even for small incremental changes in the digital input words. The buffered output ensures low output impedance and helps to improve linearity and noise immunity.

The LTC2635HMSE-LMX8#PBF has an excellent static and dynamic performance with a guaranteed monotonicity over temperature, and operates from a single 5V supply with a throughput rate of 1M samples/s, and a low 7μs settling time. It provides superb accuracy of ±2 LSB, which results in precise and reliable analog output signals.

The LTC2635HMSE-LMX8#PBF is a highly versatile and cost-effective DAC device that can be used in a number of industrial, medical, and consumer-oriented applications such as in digital-to-analog converters, SCADA systems, process control systems, audio systems, and medical diagnostic instrumentation. It provides extraordinary static and dynamic performance ensuring accurate and linear output voltages with a guaranteed monotonicity over temperature.
