Datasheet Analog Devices ADA4806-1ARJZ-R7 — 数据表

FEATURES TYPICAL APPLICATIONS CIRCUIT APPLICATIONS
Portable and battery-powered instruments and systems
High channel density data acquisition systems
Precision analog-to-digital converter (ADC) drivers
Voltage reference buffers
Portable point of sales terminals
Active RFID readers 5V C2
10µF IN+ REF VDD IN–
C1
2.7nF AD7980
13391-001 ADA4806-1
R3
20Ω GND Figure 1. Driving the AD7980 with the ADA4806-1 Sleep mode reduces the amplifier quiescent current to 74 µA
and provides a fast turn-on time of only 0.45 µs, enabling the
use of dynamic power scaling for sample rates approaching
2 MSPS. For additional power savings at lower samples rates,
the shutdown mode further reduces the quiescent current to
only 2.9 µA.
The ADA4806-1 operates over a wide range of supply voltages
and is fully specified at supplies of 3 V, 5 V and ±5 V. This
amplifier is available in a compact, 8-lead SOT-23 package and
is rated to operate over the industrial temperature range of
−40°C to +125°C. …
