PROGRAMMABLE 64 PPR INCREMENTAL MAGNETIC ROTARY ENCODER

DATA SHEET

1 General Description

2 Key Features

The AS5035 is a magnetic incremental encoder with 64

- Full turn (360°) contactless angular position encoder

quadrature pulses per revolution (8-bit resolution) and

index output.

lid Two diagnostic outputs are provided to indicate an out-of-

range condition of the magnetic field as well as movement

of the magnet in Z-axis. In addition a specific combination

of output states indicate a loss of power supply.

a The AS5035 is available in a small 16pin SSOP package. It

ill v can be operated at either 3.3V or 5V supplies.

- 2 quadrature A/B outputs with 64 pulses per revolution

(ppr), 256 edges per revolution, 1.4° per step

- Index output (one pulse per revolution)

- Accurate user programmable zero position (0.35°)

- Failure detection mode for magnet placement

monitoring and loss of power supply

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

- Small lead-free package: SSOP 16 (5.3mm x 6.2mm)

co 1.1 Benefits

l - Complete system-on-chip, including analog front end

and digital signal processing

a - 2-channel quadrature and index outputs provide an

ic alternative to optical encoders

- User programmable Zero positioning by OTP allows

easy assembly of magnet

n - Diagnostic features for operation safety

h - Ideal for applications in harsh environments due to

magnetic sensing principle

c - Robust system, tolerant to magnet misalignment, air

egap variations, temperature variations and external

Tmagnetic stray fields
