DS1211+ Details

The DS1211 Nonvolatile Controller x 8 Chip is a CMOS circuit which solves the application problem of converting CMOS RAMs into nonvolatile memories. Incoming power is monitored for an out-oftolerance condition. When such a condition is detected, the chip enables are inhibited to accomplish write protection and the battery is switched on to supply RAMs with uninterrupted power. Special circuitry uses a low-leakage CMOS process which affords precise voltage detection at extremely low battery consumption.FEATURES■ Converts full CMOS RAMs into nonvolatile memories■ Unconditionally write protects when VCC is out of tolerance■ Automatically switches to battery when power-fail occurs■ 3 to 8 decoder provides control for up to eight CMOS RAMs■ Consumes less than 100 nA of battery current■ Tests battery condition on power-up■ Provides for redundant batteries■ Power-fail signal can be used to interrupt processor on power failure■ Optional 5% or 10% power-fail detection■ Optional 20-pin SOIC surface mount package■ Optional industrial temperature range of -40°C to +85°C

FAQs

What is DS1211+?

The DS1211+ is a precision temperature-compensated silicon compander designed by Maxim Integrated. It is commonly used for audio applications where dynamic range compression and expansion are required to maintain optimal signal levels.

How Does DS1211+ Work?

The DS1211+ operates as a compander, combining compression and expansion functions to regulate audio signal levels. It uses temperature compensation to maintain consistent performance across varying environmental conditions. The compander adjusts the dynamic range of the audio signal to ensure optimal clarity and fidelity.

How Many Pins does DS1211+ have and What are the Functions of the Pinout Configuration?

The DS1211+ is housed in an 8-pin DIP (Dual Inline Package) or SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

VCC: Power supply pin.
GND: Ground pin.
VIN: Audio input signal pin.
VOUT: Companded audio output signal pin.
COMPAND: Companding control pin.
MODE: Mode selection pin.
TC: Temperature compensation pin.

What are the Pros and Cons of DS1211+?
