Featured reference designs

Analog PWM generator with 5-V, 500-kHz PWM output

Uses a triangle wave generator and comparator to generate a pulse-width-modulated (PWM) waveform with a duty cycle that is inversely proportional to the input

Single-ended-input-to-differential-output conversion circuit

Converts the differential current output of audio DACs to a single-ended voltage for driving low-impedance headphones and providing hi-fi audio in cell phones and portable audio players

Wideband optical front end

With over 120MHz of bandwidth, this complete, modular reference design can meet the demanding needs of many optical systems including OTDR, ToF, machine vision, LIDAR and defense applications

Multiplexed data acquisition for high-voltage inputs and low distortion

Implements a 16-bit, differential 4-channel, multiplexed data acquisition system at 400-KSPS throughput for industrial applications

Low-power, wireless PIR motion detector enabling 10-year coin cell battery life

Uses nano-power operational amplifiers, comparators, and the SimpleLink ultra-low power sub-1GHz wireless microcontroller (MCU) platform. Enables over 10 years battery life (CR2032)
