Produktbeschreibung
AD7998 is an 8-channel, 12bit, low power, successive approximation ADC with an I²C-compatible interface. It operates from a single 2.7V to 5.5V power supply and feature a 2µs conversion time. This parts contain an 8-channel multiplexer and track-and-hold amplifier that can handle input frequencies upto 11MHz. It provides a 2-wire serial interface that is compatible with I²C interfaces. This device normally remain in a shutdown state while not converting, and power up only for conversions. The conversion process can be controlled using the CONVST pin, by a command mode where conversions occur across I²C write operations or an automatic conversion interval mode selected through software control. It requires an external reference that should be applied to the REFIN pin and can be in the range of 1.2V to VDD. This allows the widest dynamic input range to the ADC.
- Low power consumption, sequencer operation
- Automatic cycle mode, out-of-range indicator/alert function
- I²C®-compatible serial interface supports standard, fast, and high speed modes
- Pin-selectable addressing via AS, shutdown mode current is 1µA maximum
- Signal to noise ratio is 71dB minimum at (VDD = 2.7V to 5.5V)
- Total harmonic distortion is -78dB maximum at (VDD = 2.7V to 5.5V)
- Full-power bandwidth is 11MHz typical at (VDD = 2.7V to 5.5V)
- Aperture jitter is 50ps typical at (VDD = 2.7V to 5.5V)
- Integral nonlinearity is ±1LSB maximum at (VDD = 2.7V to 5.5V)
- Operating temperature is -40°C to +85°C, package style is 20-lead TSSOP
