General Description
The MAXQ7667 smart system-on-a-chip (SoC) provides a
time-of-flight ultrasonic distance-measuring solution. The
device is optimized for applications involving large dis-
tance measurement with weak input signals or multiple
target identification. The MAXQ7667 features high signal-
to-noise ratio achieved by combining flexible electronics
with the intelligence necessary to optimize each function
as environmental and target conditions change.
An integrated burst signal generator and echo reception
components process ultrasonic signals between 25kHz
and 100kHz. Echo reception components include a pro-
grammable gain low-noise amplifier (LNA), a 16-bit
sigma-delta ADC to digitize the received echo signals,
and digital signal processing (DSP). DSP limits noise
with a bandpass filter, and creates an echo envelope
through demodulation and lowpass filtering. Input
referred noise is a low 0.7VRMS. A programmable
phase-locked loop (PLL) frequency synthesizer supplies
the reference frequency for the burst generator and the
clock for the echo receiver’s digital filter. An embedded
16-bit MAXQ20 microcontroller (C) controls all the pre-
ceding functions.
The C optimizes the burst frequency and reception
frequency for each transmission at any temperature.
The MAXQ7667 achieves smart sensing by monitoring
the echo signals and then actively changing the trans-
mitted and received parameters to obtain optimum
results. Digital filtering and burst synthesis do not
require CPU intervention. This leaves all the CPU power
available for echo optimization, communication, diag-
nostics, and additional signal processing.
The MAXQ7667 operates with three different power
supply voltages: +5V, +3.3V, and +2.5V. Two internal
linear regulators allow operation from a single +5V sup-
ply when three external power supplies are not avail-
able. Alternatively, the MAXQ7667 can control an
external pass transistor to allow operation from a single
supply voltage of +8V to +65V or more, depending on
the external component tolerance. The device is avail-
able in a 48-pin LQFP package and is specified to
operate from -40°C to +125°C.
