GENERAL DESCRIPTION
The ADA4625-1/ADA4625-2 build on Analog Devices, Inc.,
high voltage, single-supply, rail-to-rail output (RRO), precision
junction field effect transistor (JFET) input op amps, taking that
product type to a level of speed and low noise that has not been
made available to the market previously.
The ADA4625-1/ADA4625-2 provide optimal performance in
high voltage, high gain, and low noise applications. The input
common-mode voltage range includes the negative supply, and
the output swings rail to rail. This enables the user to maximize
dynamic input range in low voltage, single supply applications
without the need for a separate negative voltage power supply
for ground sense.
The combination of wide bandwidth, low noise, and low input
bias current makes the ADA4625-1/ADA4625-2 especially
suitable for phase-locked loop (PLL), active filter amplifiers and
for high tuning voltage (VTUNE), voltage controlled oscillators
(VCOs) and preamplifiers where low level signals require an
amplifier that provides both high amplification and wide
bandwidth.

Figure 1.
The ADA4625-1/ADA4625-2 are unity-gain stable, and there is
no phase reversal when input range exceeds either supply rail by
200 mV. The output is capable of driving loads up to 1000 pF
and/or 600 Ω loads.
The ADA4625-1/ADA4625-2 are specified for operation over
the extended industrial temperature range of −40°C to +125°C
and operates from +5 V to +36 V (±2.5 V to ±18 V) with specifi-
cations at +5 V and ±18 V. The devices are available in an 8-lead
SOIC package with an exposed pad (EPAD).
