3. UX output only otherwise it is PWM output only For example part number 1932SYI indicates that the device s output is PWM output In contrary 1932SYI01 means device s output is AUX output ISD1900 device PWM output can drive a speaker directly while AUX output needs to be amplified before driving a speaker Publication Release Date Jan 28 2009 Sd Revision 0 1 ISD DEMO1900 REV_A nuvoTom OOOO For demo boards with AUX output users can choose either to use the on board LM386 to amplify the ISD1900 device output signal then connect to a speaker to evaluate the sound or draw the signal out to their own amplifier for further evaluation As a reminder please check what kind of ISD1900 device is populated on your demo board before heading for further evaluation Figure 3 is attached below aiming to help user to judge what kind of ISD1900 device is on the demo board 11 ORDERING INFORMATION Product Number Descriptor Key 119 0000000 Product Name Output Type on Blank PWM Product Series 01 AUX out 19 1900 Tape amp Reel Blank None Duration A R Tape amp Reel 16 10 6 32 secs 32 213 64secs Temperature 64 426 128 secs l Industrial 40 C to 85 C Package Type S Small Outline Integrated Circuit SOIC Package Lead Free Y Lead Free Figure 3 ISD1900 ordering information gt AUX out type device has 01 ending Default set
