DKD (44-Pin PSOP3)
Self-Protection Design (Including Undervoltage, Overtemperature, Clipping, and Short-Circuit Protection) With Error Reporting
The TAS5630 is a high performance analog input Class D amplifier with integrated closed loop feedback technology (known as PurePath™ HD) with the ability to drive up to 300W (1) Stereo into 4 to 8 Speakers from a single 50V supply.

PurePath™ HD technology enables traditional AB-Amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class D amplifiers.

Unlike traditional Class D amplifiers, the distortion curve only increases once the output levels move into clipping.

PurePath™ HD technology enables lower idle losses making the device even more efficient. Coupled with TI's Class G power supply reference design for TAS563x, industry leading levels of efficiency can be achieved.

TPA2054D4
2.4 W/Ch 3-Input Audio Subsystem with Stereo Class-D and DirectPath™ Headphone Amplifier
Stereo Class-D Amp:
1.4 W into 8 from 5.0 V (10% THD + N)
1.25 W into 8 from 5.0 V (1% THD + N)
DirectPath™ Stereo Headphone Amplifier
No Output Capacitors Required
Independent Gain Select for Headphone Amplifier
Eight Programmable Maximum Headphone Voltage Limits
Two Single-Ended or One Differential Stereo Input
3:1 Input MUX with Mode Control
32-Step Volume Control for Both Input Channels
Independent Shutdown for Headphone and Class-D Amplifiers
Short-Circuit and Thermal-Overload Protection
±8 kV HBM ESD Protection on Headphone Outputs
I2C™ Interface
25-Ball 2,61 mm &#215; 2,61 mm WCSP
The TPA2054D4 features a stereo Class-D power amplifier along with a stereo DirectPath™ headphone amplifier. The TPA2054D4 has a mono differential input and two stereo single-ended (SE) inputs that can be configured as one stereo differential input. Both input channels have a 32-step volume control and the DirectPath headphone amplifier has a 4-level gain control for coarse volume adjustment. All amplifiers have output short-circuit and thermal- overload protection.

The Class-D amplifiers deliver 1.25 W into 8 at 1% THD from a 5.0 V supply, and 700 mW from 3.6 V. The DirectPath headphone amplifier features an output voltage limiter to reduce the maximum output power to one of seven possible limits. The voltage limiter is programmed through the I2C interface.

DirectPath eliminates the need for external DC- blocking output capacitors to the headphones. The built-in charge pump creates a negative supply voltage for the headphone amplifier, allowing a 0-V DC bias at the output.

The DirectPath headphone amplifier gains are +6 dB (default), 0 dB, -6 dB, and -14 dB, selected through the I2C interface. This allows the headphone volume to be different from the loudspeaker volume if both are used simultaneously.

The TPA2054D4 has a 3:1 input MUX for audio source selection. The MUX has mode control which directs the input-to-output signal path. Mode and gain controls operate from a 1.8 V compatible I2C interface.

The voltage supply range for both the Class-D amplifiers and the headphone charge pump is 2.5 V to 5.5 V. The Class-D amplifiers use a combined 7 mA and the headphone amplifier uses 10 mA of typical quiescent current. Total supply current reduces to less than 2µA.

The TPA2054D4YZK is available in a 25-ball 2,61 mm &#215; 2,61 mm WCSP package.

BQ32000 Serial RTC

Automatic Switchover to Backup Supply
I2C Interface
Supports Serial Clock up to 400 kHz
Uses 32.768-kHz Crystal
With –63-ppm to +126-ppm Adjustment
Integrated Oscillator-Fail Detection
8-Pin SOIC Package
The bq32000 device is a compatible replacement for industry standard real-time clocks.

The bq32000 features an automatic backup supply with integrated trickle charger. The backup supply can be implemented using a capacitor or non-rechargeable battery. The bq32000 has a programmable calibration adjustment from –63 ppm to +126 ppm. The bq32000 registers include an OF (oscillator fail) flag indicating the status of the RTC oscillator, as well as a STOP bit that allows the host processor to disable the oscillator. The time registers are normally updated once per second, and all the registers are updated at the same time to prevent a timekeeping glitch. The bq32000 includes automatic leap-year compensation.
