SAE800G GEG

Audio Special Purpose Overview

The Infineon SAE800G is a programmable audio tone processor IC designed for generating single, dual, or triple-tone gong signals. It operates within a supply voltage range of 2.8 V to 18 V and features a shutdown function for low standby current consumption. The device integrates the complete signal chain required for tone generation and shaping, housed in a PG-DSO-8 (SOIC-8) surface-mount package.

Audio Special Purpose Feature Summary

• Programmable single-, dual-, or triple-tone generation via E1/E2 trigger inputs
• Integrated loudness control capability
• Low standby current in shutdown mode
• Logic interface triggering
• PG-DSO-8-1 surface-mount package

Audio Special Purpose Applications

• Home chime installations
• Audio systems requiring programmable tone sequences
• Battery-operated devices due to low standby current

Audio Special Purpose Procurement Notes

This component is End-of-Life (EOL). Mouser indicates it is currently not available for sale in many regions. Designers should consult Infineon for replacement recommendations or evaluate generic programmable tone generators if pin compatibility is not required.

Audio Special Purpose Selection Notes

Select external oscillator components (RR, CC) based on the desired fundamental frequency using the formula f0 = 5 / (8 * RR * CC). Calculate the loudness resistor RL based on the load impedance RQ and supply voltage VS to ensure proper amplitude ratios. Ensure the trigger input voltages remain within the specified limits.

Audio Special Purpose Part Context

The SAE800G belongs to the SAE 800 family of bipolar ICs. It is functionally equivalent to the through-hole SAE 800 but packaged for surface mount technology. The device serves as a dedicated solution for generating musical tones in appliances and security systems without requiring complex microcontroller programming.

Audio Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Infineon directly for cross-reference recommendations or evaluate generic programmable tone generators if pin compatibility is not required.
