The TC500A is a precision analog front end dual slope A/D converter having a maximum resolution of 17 bits plus sign. Dual Slope Analog to Digital Converter This type of an ADC is known as the dual slope ADC because it integrates and deintegrates a voltage signal with the help of a reference voltage, Vref. Usually the dual slope ADC is thus a little simpler and needs less precision resistors. Most ADC applications can be classified into four broad market segments: (a) ... (dual-slope, triple-slope, quad-slope, etc.) Dual-Slope ADC Architecture A dual-slope ADC (DS-ADC) integrates an unknown input voltage (V IN) for a fixed amount of time (T INT), then "de-integrates" (T DEINT) using a known reference voltage (V REF) for a variable amount of time (see Figure 2). High-Performance, Stand-Alone ADCs for a Variety of Embedded Systems Applications. If we know the rate, and we measure the time, we know how high the stairs are. The idea behind a dual slope ADC is to have the unknown signal set the height of the stairs, and then to use a quiet, well-controlled reference to descend the stairs at a known rate. Which of following is not a type of ADC? Dual-Slope ADC Architecture A dual-slope ADC (DS-ADC) integrates an unknown input voltage (VIN) for a fixed amount of time (TINT), then "de-integrates" (TDEINT) using a known reference voltage (VREF) for a variable amount of time (see Figure 2). The name of this analog to digital converter comes from the fact that the integrator output changes linearly over time, with two different slopes during the conversion process. 6.2 Dual-slope converter Figure 7.

In the dual-slope converter, an integrator circuit is driven positive and negative in alternating cycles to ramp down and then up, rather than being reset to 0 volts at the end of every cycle. [3] Done. A dual-slope integrating ADC is best suited for low-speed applications where good power-supply rejection is desired. However, for the high accurate measurements authors developed their own A/D converter circuits based on the multiple dual-slope AD 6½ and 7½ digits AD conversion method.

The TC500 is 10 mW precision analog front end with dual slope analog-to-digital converter. 3 . Figure 2. The basic principle of this type of A/D converter is that the unknown analog input voltage is approximated against an n-bit digital value by trying one bit at a time, beginning with the MSB. Introduction If one electronic component is to be nominated as the workhorse inside test-and-measurement equipment, it would be the analog-to-digital converter (ADC). ADCs (dual-slope, triple-slope, quad-slope, etc.) Dual-slope ADCs are used in applications demanding high accuracy. The dual slope DAC can use the same resistor and is this more stable in ADC gain. Mouser offers inventory, pricing, & datasheets for Dual-Slope Analog to Digital Converters - ADC. See application note 1041, "Understanding Integrating ADCs" for more information. A simplified diagram is shown in Figure 1, and the integrator output waveforms are shown in Figure 2. [5] Voltage follower application (solve load down the power supply for the load to receive enough voltage it needs). Component Dual-slope integration. The conversion time is maintained constant in successive approximation type ADC, and is proportional to the number of bits in the digitaloutput, unlike the counter and continuous type A/D converters. the dual-slope converter. 2.
