MAXIM INTEGRATED PRODUCTS DS1881E-050+ Non Volatile Digital Potentiometer, Configurable, 45 kohm, Dual, I2C, Log (Audio), ± 20%, 4.5 VThe DS1881E 050+ is a dual, non volatile (NV) audio taper digital potentiometer in 16 pin TSSOP package. This device is a log taper potentiometer which is designed to operate in audio systems that require 5V signal levels. The potentiometer settings can be stored in EEPROM so that they are retained when the power is cycled. DS1881 has separate supplies for the potentiometers (VCC) and the communication circuitry (VDD). For clickless popless operation,
The DS1881E-050+ is a dual, non-volatile (NV) audio taper digital potentiometer in 16 pin TSSOP package. This device is a log taper potentiometer which is designed to operate in audio systems that require 5V signal levels. The potentiometer settings can be stored in EEPROM so that they are retained when the power is cycled. DS1881 has separate supplies for the potentiometers (VCC) and the communication circuitry (VDD). For clickless/popless operation, a zero-crossing detector allows the wiper position to change when there is no voltage across the potentiometer. It minimizes crosstalk and the two digital potentiometers and provides 0.5dB channel to channel matching to prevent volume differences between channels. Total harmonic distortion (THD) is also minimal as long as the wiper drives a high-impedance load.
- Supply voltage range is 4.5V to 5.5V
- Operating temperature range from -40°C to 85°C
- I²C compatible serial interface
- Operates with 64 positions with 1dB attenuation per step
- Two attenuation configuration options provide optimum flexibility
- End to end resistance is 45Kohm at ±20% tolerance and temperature coefficient is 300ppm/°C
- Low THD+N and crosstalk
- Potentiometer settings configurable as non-volatile or volatile
- Three address pins allow up to 8 devices on I²C bus

Soild
Size: Medium
The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it.
The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.
