8 BIT PROGRAMMABLE HIGH SPEED

MAGNETIC ROTARY ENCODER

DATA SHEET

General Description

1.2 Key Features

•

360°contactless angular position encoding

The AS5030 is a contactless magnetic rotary encoder for

accurate angular measurement over a full turn of 360°.

It is a system-on-chip, combining integrated Hall elements,

analog front end and digital signal processing in a single

device.

Two digital 8-bit absolute outputs:

- Serial interface and

- Pulse width modulated (PWM) output

To measure the angle, only a simple two-pole magnet,

rotating over the center of the chip is required.

The absolute angle measurement provides instant indication

of the magnet’s angular position with a resolution of 8 bit =

256 positions per revolution. This digital data is available as

a serial bit stream and as a PWM signal.

In addition to the angle information, the strength of the

magnetic field is also available as a 6-bit code.

Data transmission can be configured for 1-wire (PWM), 2-

wires (CLK, DIO) or 3-wires (CLK, DIO, CS).

•

User programmable zero position

High speed: up to 30,000 rpm

Direct measurement of magnetic field strength

allows exact determination of vertical magnet

distance

•

Serial read-out of multiple interconnected

AS5030 devices using daisy chain mode

A software programmable (OTP) zero position simplifies

assembly as the zero position of the magnet does not need

to be mechanically aligned.

•

Wide magnetic field input range: 20 ~ 80mT

Wide temperature range: - 40°C to + 125°C

Small Pb-free package: TSSOP 16

Power Down Mode together with fast startup- and

measurement cycles allows for very low average power

consumption and makes the AS5030 also suitable for battery

operated equipment.
