Fe a tu r e s

Selectable Power Modes as low as 2 mA (3V)

Power Down Mode to 400 uA

Operates from 3.0V to 5.5 VDC

5 6 pole Bandpass filters in one package

Digitally controlled gain stage

The MSTHDA is a single chip 1/6 octave-wide

5 harmonic Total Harmonic Distortion analyzer

whose center frequencies are controlled by a

single master clock. The center frequencies are

set at the fundamental, second harmonic, third

harmonic, fourth harmonic and fifth harmonic fre-

quency. The sample to corner is 25:1 for the

fifth-harmonic output and 125:1 at the funda-

mental output (Double Sampled). The fifth har-

monic output is 3.4 MHz when clocked at 42.5

MHz(MSTHDA-1).

Two Uncommitted Op Amps

No Microprocessor Needed

Multi-standard RFID Readers (MSTHDA-1)

Real-Time DistortionAnalysis

Audio and Ultrasonic Analysis

Vibration Analysis

The MSTHDA includes two uncommitted op

amps for adding additional fixed gain for micro-

phone or other low level applications. A digital-

ly programmable gain stage provides 0, 10 or

20 dB of gain. The PD pin selects power

down, low power for ultrasonic applications and

regular power for high frequency operation.
