Unity-Gain Stable, Ultralow Distortion, 1 Nv/√Hz Voltage Noise, High Speed Op Amp (Ada4899); Ultralow Noise, Ldo Xfet Voltage References With Current Sink And Source (Adr441B) - Analog Devices ADSP-CM419F EZ-KIT Manual

Unity-Gain Stable, Ultralow Distortion, 1 nV/√Hz Voltage Noise, High Speed Op Amp (ADA4899)
The ADM3252E conforms to the EIA/TIA-232E and ITU-T V.28 specifications and operates at data rates of up to
460 kbps. Four external 0.1 µF charge pump capacitors are used for the voltage doubler/inverter, permitting opera-
tion from a single 3.3 V or 5 V supply. The ADM3252E is available in a 44-ball, chip scale package ball grid array
(CSP_BGA) and is specified over the −40°C to +85°C temperature range.
Unity-Gain Stable, Ultralow Distortion, 1 nV/√Hz Voltage Noise,
High Speed Op Amp (ADA4899)
The ADA4899-1 is an ultralow noise (1 nV/√Hz) and distortion (<−117 dBc @1 MHz) unity-gain stable voltage
feedback op amp, the combination of which makes it ideal for 16-bit and 18-bit systems. The ADA4899-1 features
a linear, low noise input stage and internal compensation that achieves high slew rates and low noise even at unity
gain. The Analog Devices, Inc. proprietary next-generation XFCB process and innovative circuit design enable such
high performance amplifiers.
The ADA4899-1 drives 100 Ω loads at breakthrough performance levels with only 15 mA of supply current. With
the wide supply voltage range (4.5 V to 12 V), low offset voltage (230 µV maximum), wide bandwidth (600 MHz),
and slew rate (310 V/µs), the ADA4899-1 is designed to work in the most demanding applications. The
ADA4899-1 also features an input bias current cancellation mode that reduces input bias current by a factor of 60.
The ADA4899-1 is available in a 3 mm × 3 mm LFCSP and an 8-lead SOIC package. Both packages feature an
exposed metal paddle that improves heat transfer to the ground plane, which is a significant improvement over tradi-
tional plastic packages. The ADA4899-1 is rated to work over the extended industrial temperature range, −40°C to
+125°C.
Ultralow Noise, LDO XFET Voltage References with Current Sink
and Source (ADR441B)
The ADR44x series is a family of XFET® voltage references featuring ultralow noise, high accuracy, and low tem-
perature drift performance. Using Analog Devices, Inc., patented temperature drift curvature correction and XFET
(eXtra implanted junction FET) technology, voltage change vs. temperature nonlinearity in the ADR44x is greatly
minimized.
The XFET references offer better noise performance than buried Zener references, and XFET references operate off
low supply voltage headroom (0.5 V). This combination of features makes the ADR44x family ideally suited for
precision signal conversion applications in high-end data acquisition systems, optical networks, and medical applica-
tions.
The ADR44x family has the capability to source up to 10 mA of output current and sink up to −5 mA. It also
comes with a trim terminal to adjust the output voltage over a 0.5% range without compromising performance.
Offered in two electrical grades, the ADR44x family is avail-able in 8-lead MSOP and narrow SOIC packages. All
versions are specified over the extended industrial temperature range of −40°C to +125°C.
