1 Temperature ranges are as follows: A, B grades: –40°C to +85°C; C, D grades: –40°C to +125°C.
2 The voltages, SIN, SINLO, COS, and COSLO, relative to AGND, must always be between 0.15 V and AVDD 0.2 V.
3 All specifications within the angular accuracy parameter are tested at constant velocity, that is, zero acceleration.
4 The velocity accuracy specification includes velocity offset and dynamic ripple.
5 For example when RES0 = 0 and RES1 = 1, the position output has a resolution of 12 bits. The velocity output has a resolution of 11 bits with the MSB indicating the
direction of rotation. In this example, with a CLKIN frequency of 8.192 MHz the velocity LSB is 0.488 rps, that is, 1000 rps/(211).
6 The clock frequency of the AD2S1210 can be supplied with a crystal, an oscillator, or directly from a DSP/microprocessor digital output. When using a single-ended
clock signal directly from the DSP/microprocessor, the XTALOUT pin should remain open circuit and the logic levels outlined under the logic inputs parameter in Table 1 apply.
