Detailed Description Application notes
Analog Channel Inputs ATS308T
ATS308T provides independent analog channels (Ch1 Ch2) offset adjustment inputs (Offset1 Offset2) every analog channel. There usable steps totally each channel besides steps dead band, steps both sides dead band course. Considering offset adjustment analog channels, Offset1 (for Ch1) Offset2 (For Ch2) inputs provided moving channel input voltage range down whole, thereby inputs being dead band.
usage OFFSET adjustment function selectable. input voltage OFFSET should Vref placing resistors whose value equal, unused
Notice that analog channel input range absolutely meet requirements voltage that generated variable resistor (2.7V reference used). resistor's Total-RotationAngle value effective input range must above 50°. input rotation angle less than 50°, some steps should losing. resolve problem? Using external higher reference Voltage good way.
output signals ATS308T
base band signal that used wireless application. signal that modulated somewhat carrier signal. Notice that carrier signal frequency half oscillator's frequency. application, different carrier frequency throughout changing oscillator's resistor.
function ATS308T
ATS308T particularly provides function designs that realize car's motorial form controlling tank (4WD)'s motions through (2WD)'s handles (one driving Speed, another steering servo)
Function Outputs ATS308R corresponding ATS308T's analog channel inputs
When signal come into input that from amplifies circuit, ATS308R will decode encoded signal, produce corresponding outputs. input voltage equal above than 1.7V, will High Logic will hold Logic Level. Also input voltage equal less than 1.0V, will High Logic will hold Logic Level. others input situations ATS308T, duty ratio signal will change linearly. signal period 8ms(when oscillator's frequency 128KHz), first step's duty 12.5%, then increase 6.25% ratio step step, until High Logic. course output active when another match inactive (Low logic).

critical controlling steering servo. Just like driving car, people know many steering wheel angles should rotated depending eyes. feedback eyes must necessary. steering servo applications, insure rotation angles lies outsides feedback. That feedback. outputs (LEFT RIGHT) chip drive motor driving circuit, then rotation motor affects level, level's feedback chip makes chip changing outputs what CHANNEL wanted after signal processing. Relation between chip outputs feedback voltage indirect. motor geardown mechanical architecture play important role. Figure blow shows this close relation.

From figure above, easy find that dead band input move from position another position. When ATS308T's analog input dead band, then adjust input voltage until there active outputs LEFT RIGHT, just measurement input voltage shows that voltage about 1.35V(two steps' dead band) (actual voltage range depending actual device reference voltage). Notice that analog channel input range absolutely meet requirements voltage that generated variable resistor (2.7V reference used). resistor's Total-RotationAngle value effective input range must above 50°. input rotation angle less than 50°, some steps should losing. resolve problem? Using external higher reference Voltage good way.
(6)Adjustment Oscillator ATS308T's input
Adjustment oscillator used regulating outputs (M2, M2N, LEFT, RIGHT) corresponding analog Channel input. When frequency Main oscillator equal adjustment oscillator's, outputs about just like what forth descriptions above say. value adjustment oscillator's frequency changed, outputs' signal duty ratio will vary linearly down Adjustment function about very important designs. example, different value first step's duty driving steering servo needed because different mechanical architecture motor characteristics different types steering motors. best steering servo characteristics realized adjusting suitable value oscillator adjustment.
