The ADS1000 is fabricated in a small-geometry
low-voltage process. The analog inputs feature
protection diodes to the supply rails. However, the
current-handling ability of these diodes is limited, and
the ADS1000 can be permanently damaged by

approximately 300mV beyond the rails for extended
periods. One way to protect against overvoltage is to
place current-limiting resistors on the input lines. The
ADS1000 analog inputs can withstand momentary
currents of as large as 10mA.

Any data converter is only as good as its reference.
For the ADS1000, the reference is the power supply,
and the power supply must be clean enough to
achieve the desired performance. If a power-supply
filter capacitor is used, it should be placed close to

pin, with no vias placed between the
capacitor and the pin. The trace leading to the pin
should be as wide as possible, even if it must be
necked down at the device.
If the ADS1000 is driven by an op amp with high
voltage supplies, such as
±
12V, protection should be
provided, even if the op amp is configured so that it
will not output out-of-range voltages. Many op amps
seek to one of the supply rails immediately when
power is applied, usually before the input has
