Description
The SI-1125HD is a CMOS Serial E2PROM, internally organized 16K x 8.The device features a serial inter-face
and software protocol allowing operation on a simple two wire bus.Three device select inputs (S0–S2) allow up
to eight devices to share a common two wire bus.A Write Protect Register at the highest address loca-tion,
FFFFh, provides three write protection features:Software Write Protect, Block Lock Protect,and Programmable
Hardware Write Protect.
Features
>Save Critical Data with Programmable Block Lock Protection
—Block Lock (0, 1/4, 1/2, or all of E PROM Array)
—Software Write Protection
—Programmable Hardware Write Protect
>In Circuit Programmable ROM Mode
>400KHz 2-Wire Serial Interface
—Schmitt Trigger Input Noise Suppression
—Output Slope Control for Ground Bounce Noise Elimination
25W Dual Channel Amp with tone control circuit is module by Sanken, the module is installable in feedback circuit. Tone control is a type of equalization used to make specific frequencies in an audio signal softer or louder. It consists of a network of filters which modify the signal before it is fed to output device.
Following are basic features of SI-1125HD;
1- Ripple Filter
2- Feedback control
3- Harmonic Distortion filter
The absolute maximum rating and Characteristics @ temperature of 25°C for 8 ohm load per channel is;
1- Supply Voltage +/- 25V
2- Supply Current 0.8A
3- Output Power 25W
4- Power Bandwidth 10 to 20kHz
5- Frequency Response 10 to 100kHz
6- Voltage Gain 40dB
7- Output Noise Voltage maximum 2.0mV
Major Pin Configuration for the modules as following;
1- Pin 1/16 Ripple Filter Capacitor (+)
2- Pin 3/14 Ripple Filter Capacitor (-)
3- Pin 6/11 Bootstrap Capacitor
4- Pin 8/10 is channel 2 and channel 1 Output respectively
5- Pin 5/12 Feedback resistor
These type of tone controls are found on many sound systems: radios, portable music players, public address systems, and musical instrument amplifiers. Power Derating based on thermal response shows that the thermal resistance between Junction and Heat Sink is maximum 3.3°C/W.
