 LTC2633HTS8-LO8#TRMPBF Application field and Working PrincipleData Acquisition - Digital to Analog Converters (DAC):The LTC2633HTS8-LO8#TRMPBF is a Low-Power 8-Channel 16-/12-/8-Bit ±10V/V Voltage Output DAC family with Event Detect and Multiple Slope Soft Span and enables simple, low-power, accurate, single-supply analog output performance from a digital input. The family includes both dual and quad versions, with a range of effectively scaled output ranges from ±10V to ±20mV, as well as adjustable soft spans for output ranges from ±10V to ±1.25V. The output-range configuration flexibility, combined with the low-power and small size features, make the family an ideal fit for several data acquisition applications.Working Principle:LTC2633HTS8-LO8#TRMPBF adopts a multi-level architecture, consisting of an 8-bit, 10-bit, or 12-bit DAC core followed by a 3rd-order VOUT, wide range programmable output stage. Full scale is independently programmed for each DAC output over a range of ±10V to ±20mV (or adjustable/adjustable soft span ranges from ±10V to ±1.25V). The DAC core uses a differential current architecture with a current output scale programmed for each channel. The Digital-to-Analog (DAC) core has an uncompensated INL of ±3LSB offset, ±2LSB gain, 1LSB liner-to-Logarithm (Lin2Log) accuracy, and settling time of 450ns typically for 10V/V full scale change. The power supply rejection ratio (PSRR) is typically 80dB at 100Hz with a Power Dissipation of < 70mW. The five-bit wide temperature coefficient allows temperature-compounded performance of 0.5LSB usually achievable with a single 3rd order network.Application Field:The LTC2633HTS8-LO8#TRMPBF is well suited for use in portable battery operated data acquisition applications such as pH measurement, weight scale indication, and voltage/current monitor/control. The family\'s small size, three voltage reference choices and wide input range make it appropriate for embedded applications.The LTC2633HTS8-LO8#TRMPBF is suitable for low-noise, high-accuracy industrial, medical and test and measurement applications such as ATE systems and process measurement. With its low-power and high-resolution output, the family is also well suited for applications in functional test and calibration. The low-power and wide output range combined with low voltage reference input makes it well suited for standalone ADC and DAC systems such as gain/attenuators, balancing circuits, or circuit emulation systems. The family\'s 12-/10-/8-bit range adjustment ability allows for differential/multi-channel acquisitions.The LTC2633HTS8-LO8#TRMPBF family offers exceptional flexibility in terms of output range, temperature coefficient and power supply performance, making it an ideal fit for many applications. The low-power feature, combined with the wide range of output range and the programmable temperature coefficient, make the family an excellent choice for portable data acquisition. The high accuracy and power supply rejection features make the LTC2633HTS8-LO8#TRMPBF an ideal solution for industrial and medical applications as well. The low-power and wide range of output range also make it suitable for usage in automated test equipment, while the low-voltage reference input makes it suitable for standalone ADC and DAC systems.
