ADM6315 - Open-Drain Microprocessor Supervisory Circuit

programmable DSP. The easy to use SigmaStudio+™ software allows the user to graphically configure a custom sig-
nal processing flow using blocks such as biquad filters, dynamics processors, level controls, and GPIO interface con-
trols.
ADAU1701 programs can be loaded on power-up either from a serial EEPROM through its own self-boot mecha-
nism or from an external microcontroller. On power-down, the current state of the parameters can be written back
to the EEPROM from the ADAU1701 to be recalled the next time the program is run.
Two Σ-Δ ADCs and four Σ-Δ DACs provide a 98.5 dB analog input to analog output dynamic range. Each ADC
has a THD + N of −83 dB, and each DAC has a THD + N of −90 dB. Digital input and output ports allow a
seamless connection to additional ADCs and DACs. The ADAU1701 communicates through an I2C bus or a 4-
wire SPI port.
ADM6315 - Open-Drain Microprocessor Supervisory Circuit
The ADM6315 is a reliable voltage-monitoring device that is suitable for use in most voltage-monitoring applica-
tions.
The ADM6315 is designed to monitor as little as a 1.8% degradation of a power supply voltage. The ADM6315
can monitor all voltages (at 100 mV increments) from 2.5 V to 5 V.
Included in this circuit is a debounced manual reset input. RESET can be activated using an ordinary switch (pull-
ing MR low), a low input from another digital device, or a degradation of the supply voltage.
The manual reset function is very useful, especially if the circuit in which the ADM6315 is operating enters into a
state that can be detected only by the user. Allowing the user to reset a system manually can reduce the damage or
danger that could otherwise be caused by an out-of-control or locked-up system.

BD28623MUV - Class D Speaker Amplifier

The BD28623MUV is a Class D Speaker Amplifier designed for Flat-panel TVs in particular for space-saving and
low-power consumption. This IC delivers an output power of 20W+20W.
LT8609 - 2A/3A Peak Synchronous Step-Down Regulator with
2.5μA Quiescent Current
The LT8609 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that
consumes only 1.7μA of non switching quiescent current. The LT8609 can deliver 2A of continuous current with
peak loads of 3A (<1sec). Burst Mode operation enables high efficiency down to very low output currents while
keeping the output ripple below 10mVP-P. A SYNC pin allows synchronization to an external clock, or spread spec-
trum modulation for low EMI operation. Internal compensation with peak current mode topology allows the use of
small inductors and results in fast transient response and good loop stability. The EN/UV pin has an accurate 1V
threshold and can be used to program VIN UVLO or to shut down the part. A capacitor on the TR/SS pin
