New AP89 K Series - 341 Sec OTP IC

Model : AP 89341 K
Price : Rs. 125.00/-
Weight : 3.00 Grams

Description

aP89341K high performance Voice OTP is fabricated with Standard CMOS process with embedded 8M bits EPROM. It can store up to 341 sec voice message with 4-bit ADPCM compression at 6KHz sampling rate. 16-bit PCM and 8-bit PCM is also available as user selectable option. User selectable triggering and output signal options provide maximum flexibility to various applications.Built-in resistor controlled oscillator, 16-bit current mode DAC output and 14-bit current mode PWM direct speaker driving output minimize the number of external components. PC controlled programming and developing software available.
