1. CHARACTERISTICS AND SPECIFICATIONS
• Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions.
• Typical performance characteristics and specifications are derived from measurements taken at nom-
inal supply voltages and T
A
= 25°C.
• DGND = 0 V, all voltages with respect to 0 V.
SPECIFIED OPERATING CONDITIONS
Notes: 1. VA- must be the most negative voltage to avoid potential SCR latch-up conditions.
2. VD must conform to Digital Supply Differential under Absolute Maximum Ratings.
ABSOLUTE MAXIMUM RATINGS
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
Notes: 3. Transient currents up to 100mA will not cause SCR latch-up.

ANALOG CHARACTERISTICS (CONT.)
Notes: 7. Common mode signals pass through the differential amplifier architecture.
8. Absolute gain accuracy tests the matching of x1 gain across multiple CS3302 devices.
9. Relative gain accuracy tests the tracking of x1,x2, x4,x16,x32,x64 gain relative to x8 gain on a single
CS3302 device.
10. Specification is for the parameter over the specified temperature range and is for the CS3302 device
only. It does not include the effects of external components.
11. Offset voltage is tested with the amplifier inputs connected to the internal 800Ω termination.
12. The absolute offset after calibration specification applies to the effective offset voltage of the CS3302
output when used with the CS5371/72 modulator and CS5376A digital filter, and is measured from the
digitally calibrated output codes of the CS5376A.
13. The CS3302 offset calibration is performed digitally with the CS5371/72 modulator and CS5376A digital
filter and includes the full scale signal range. Calibration offsets of greater than +
5% of full scale will
begin to subtract from system dynamic range.
