CALIBRATION PROCEDURE:

WITH E

C

= 1.0V, ADJUST POTENTIOMETER TO SET f = 1.000kHz WITH

E

C

= 8.0V, ADJUST TRIMMER CAPACITOR TO SET f = 8.000kHz. LINEARITY

WILL TYPICALLY BE WITHIN ±0.1% OF FS FOR ANY OTHER INPUT.

DUE TO DELAYS IN THE COMPARATOR, THIS TECHNIQUE IS NOT SUITABLE

FOR MAXIMUM FREQUENCIES ABOVE 10kHz. FOR FREQUENCIES ABOVE

10kHz THE AD537 VOLTAGE-TO-FREQUENCY CONVERTER IS RECOMMENDED.

A TRIANGLE-WAVE OF ±5V PK APPEARS ACROSS THE 0.01µF CAPACITOR: IF

USED AS AN OUTPUT, A VOLTAGE-FOLLOWER SHOULD BE INTERPOSED.

CALIBRATION PROCEDURE:

WITH MODE SWITCH IN ‘RMS + DC’ POSITION, APPLY AN INPUT OF +1.00V DC.

ADJUST ZERO UNTIL OUTPUT READS SAME AS INPUT. CHECK FOR INPUTS

OF ±10V; OUTPUT SHOULD BE WITHIN ±0.05% (5mV).

ACCURACY IS MAINTAINED FROM 60Hz TO 100kHz, AND IS TYPICALLY HIGH

BY 0.5% AT 1MHz FOR V

IN

= 4V RMS (SINE, SQUARE, OR TRIANGLULAR-WAVE).

PROVIDED THAT THE PEAK INPUT IS NOT EXCEEDED, CREST FACTORS UP

TO AT LEAST 10 HAVE NO APPRECIABLE EFFECT ON ACCURACY.

INPUT IMPEDANCE IS ABOUT 10kΩ; FOR HIGH (10MΩ) IMPEDANCE, REMOVE

MODE SWITCH AND INPUT COUPLING COMPONENTS.

FOR GUARANTEED SPECIFICATIONS THE AD536A AND AD636 ARE OFFERED

AS A SINGLE PACKAGE RMS-TO-DC CONVERTER.
