ISL22102

Dual, Audio, Push-button Controlled Potentiometer (XDCP™)

Data Sheet

January 14, 2010

FN6788.1

32 Tap, Push-button, Dual Audio

Logarithmic Potentiometer with Buffer

Amplifiers and Audio Detection

Features

• Dual Audio Control – Two 32 Taps Log Pots

• Buffered Wiper Outputs

The ISL22102 integrates two digitally controlled

• Audio Detection with Threshold Input and Controlled

Delay

potentiometers (DCP) with buffered wiper outputs and an

internal bias voltage generator (VB) on a monolithic CMOS

integrated circuit. The wiper position is adjusted by the user

through simple Up and Down push buttons, ideal for stereo

volume control in audio applications.

• Zero Amplitude Wiper Switching (ZAWS)

• Simple Push-button Interface

• Auto Increment/decrement After 1s Button Press

• Standby Mode

Each potentiometer is implemented using 31 polysilicon

resistors in a logarithmic array. Between each of the

resistors are tap points connected to the wiper terminal

through switches. When powered up, the wipers are reset to

the -20dB position.

• Mute Function

• Total Resistance: 18.5kΩ each DCP (Typical)

• Voltage Operation

- VCC = 2.7V to 5.5V

- AVCC = 2.7V to 5.5V

In addition to the ISL22102’s low noise design, the ISL22102

also contains a zero-crossing detection circuitry to further

minimize click and pop noise during volume transition.

• Temp Range = -40°C to +85°C

The internal VB generator of the ISL22102 provides a

precision middle scale voltage reference that reduces

external circuitry and simplifies application design.

• Package Options

- 20 Ld TSSOP

- 20 Ld QFN

The ISL22102 implements two power saving techniques for

power critical applications. It is a Standby Mode that can be

enabled to reduce the power consumption of the part when

DCP is not in use. The part also has Audio Detection

• Pb-Free (RoHS Compliant)

Audio Performance

circuitry that provides an indication FLAG to external devices

and services. The FLAG can be delayed through D0, D1 and

D2 pin configuration. By connecting the FLAG to the standby

pin (SB), it will automatically put the part into Standby Mode.

• 0dB to -72dB Volume Control

• -90dB Mute

• SNR: -90dB

• THD+N: 0.01% @ 1kHz

• Crosstalk Rejection: -100dB @ 1kHz

• Channel-to-Channel Variation: ±0.1dB

• Mid point 3dB-Cutoff: 100kHz
