PT2361 Datasheet | PTC

DESCRIPTION PT2361 is a Voice Changer IC utilizing CMOS Technology specially designed for toys, masks, telephone systems and other voice applications. It features three selectable voice effects, namely: amplifying voice, robotic voice and transposing voice (higher or lower). The input audio signals are sampled into digital signals which are rearranged to produce a totally different voice effect. Pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages. FEATURES - CMOS Technology - Low Power Consumption - Selectable Voice Effects: Amplifying Voice, Robotic Voice and Transposing Voice (Higher or Lower) - No External Memory needed - Wide Operating Voltage Range: 3.0V to 5.5V - Variable Resistors / Switches may be used for Transposed- Voice Effect Adjustment - Available in C.O.B. or 28 Pins, SOP Package APPLICATIONS - Toy - Mask - Telephone System - Other Voice Application PT2361 v1.0 Page 1 November 2002 Voice Changer IC PIN CONFIGURATION LPF1OUT LPF1IN MICOUT MICIN VCC REF AGND NC NC DGND WOSCI WOSCO S1 S2 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Tel : 886-2-66296288 Fax: 886-2-29174598 URL: http://.princeton..tw 28 LPF2OUT 27 LPF2IN 26 OP2OUT 25 OP2IN 24 OP1IN 23 OP1OUT 22 CC1 21 CC2 20 ROSCO 19 ROSCI 18 ROB 17 DIN 16 NRL 15 SEL PT2361 v1.0 Page 2 November 2002 Voice Changer IC Tel : 886-2-66296288 Fax: 886-2-29174598 URL: http://.princeton..tw APPLICATION CIRCUIT VDD 0.1u 100u 47u 10P 15K 1K 1K 47P 4.7K 0.1U REF AGND DGND WOSCI WOSCO S1 S2 SEL NRL ROB...
