Voice Changer IC Tel : 886-2-66296288 Fax: 886-2-29174598 URL: http://www.princeton.com.tw PT2361 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://www.princeton.com.tw PT2361 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...
