ProxSense® Series
IQS213/A Datasheet
IQSwitch® - ProxSense® Series
3-Channel Capacitive Touch/Swipe Function Controller
Overview
Unparalleled Features
Sub 5µA* current consumption (“Zero-Power” electronic switch).
Internal Capacitor Implementation (ICI) – Reference capacitor on-chip
Automatic Tuning Implementation (ATI) - Automatic tuning for optimal operation in various
environments & compensation against sensitivity reducing objects
IQS213A advised for applications with high load-capacitances and high sensitivity
requirements.
The IQS213(A) ProxSense® IC is a fully integrated two or three channel capacitive swipe function
sensor with market leading sensitivity and automatic tuning of the sense electrodes. The
IQS213(A) provides a minimalist implementation requiring few external components, with OTP-
option settings and an I2C-compatible interface that allow configuration for numerous applications.
Main Features
2 or 3 Channel (Projected or Self Capacitance) Input device

4.2.2 Power Supply and PCB Layout
Azoteq IC's provide a high level of on-chip hardware and software noise filtering and ESD
protection (refer to application note “AZD013 – ESD Overview”). Designing PCB's with better
noise immunity against EMI, FTB and ESD in mind, it is always advisable to keep the critical noise
suppression components like the de-coupling capacitors and series resistors in Figure 4.2 as close
as possible to the IC. Always maintain a good ground connection and ground pour underneath the
IC. For more guidelines please refer to the relevant application notes as mentioned in Section
4.2.3.
