FAQ

Q1: What is the function of this product?
A:The AVI-C series is a high-precision voltage/frequency conversion circuit that can simultaneously convert the current signal (maximum ±80mA) of a triaxial accelerometer into a frequency signal output up to 512kHz. It is suitable for inertial navigation systems, industrial measurement, and sensor signal conditioning.

Q2: What is the difference with the AVI-B series?
A: AVI-C: Utilizing domestically produced components, it features a small size (48×40×8mm), low power consumption, low temperature drift, and strong controllability.
AVI-B: Slightly thicker (48×40×11mm), it offers high versatility.
While the two models offer similar performance, the AVI-C emphasizes miniaturization and domestic production.
 
Q3: What are the power requirements?
A:VCC = +15V ±3%
VEE = -15V ±3%
VDD = +5V ±3%
Low power consumption: +15V and -15V supply current ≤0.03A, +5V supply current ≤0.10A.
