Avago Technologies' reflective optical encoders suit low power systems



AEDR-87xx 3-channel reflective optical encoder devices

Avago Technologies, a leading supplier of analog interface
components for wireless, wireline, and industrial applications, today
announced a series of 3-channel reflective optical encoder devices,
the AEDR-87xx. The devices are ideal for use in low power miniaturized
motion control systems such as stepper motors, electrical actuators,
piezoelectric drives and portable medical appliances.

Expanding upon previous generation devices, the AEDR-87xx with
encoding resolution up to 318 lines per inch (LPI) supports 3.3V and 5V
supply voltage for low power applications and dual analog outputs
interfacing directly with external interpolator for high precision
motion control measurements. The devices are packaged in industry's
smallest form factor for 3-channel reflective optical encoder.

AEDR-87xx Product Highlights
-- 3 Channel Outputs Including One Index Digital Output
-- Dual Channel Digital Outputs (AEDR-871x)
-- Dual Channel Analog Outputs (AEDR-872x)
-- Built-in Interpolator for 4x, 8x and 16x Interpolation (AEDR-871x)
-- Built-in Automatic LED Current Regulation
-- Encoding Resolution: 318 LPI (up to 1.25um pitch)
-- Power Supply Voltage: 3.3 or 5 V (AEDR-871x), 5 V (AEDR-872x)
-- Operating Temperature Range: -20 to +85 degreesC
-- Compact Size: 3.95 mm (L) x 3.4 mm (W) x 0.956 mm (H)

"Reflective optical encoder technology is vital to many miniaturized
motion control systems. As modern appliances get smaller in size and
consume less power, so too are the critical components such as a motion
control encoder embedded inside many of these appliances," said Hassan
Hussain, vice president and general manager of the Motion Control
Product Division (MCPD) at Avago. "Avago's latest AEDR-87xx is the
best-in-class reflective optical encoder solution with added
flexibility addressing a wide range of design challenges for modern
miniaturized motion control systems."

Pricing and Availability
The AEDR-8710 and AEDR-8723 are priced starting at $15 and $22 USD,
respectively, each in 10,000 piece quantities. Samples and production
quantities are available now.
