The OPA140 family is a series of low-power JFET input amplifiers that feature good
drift and low input bias current. The rail-to-rail output swing and input range that
includes V- allow designers to take advantage of the low noise characteristics of
JFET amplifiers while also interfacing to modern, single-supply, precision ADCs
and DACs. The OPA140 achieves 11MHz unity-gain bandwidth and a 20V/µs slew
rate while consuming only 1.8mA (typ) of quiescent current.

The OPA377 family of operational amplifiers are wide-bandwidth CMOS amplifiers
that provide very low noise, low input bias current and low offset voltage while
operating on a low quiescent current of 0.76mA (typ).
The OPA377 op amps are optimized for low-voltage, single-supply applications.
The exceptional combination of AC and DC performance make them ideal for a
wide range of applications, including small signal conditioning, audio and active
filters. In addition, these parts have a wide supply range with excellent PSRR,
making them attractive for applications that run directly from batteries without
regulation.

The OPA171 amplifier family is a series of 36V low-noise operational amplifiers
that feature single supply, and micropackages with the ability to operate on
supplies ranging from +2.7V (±1.35V) to +36V (±18V). They offer good offset, drift
and bandwidth with low quiescent current. Single, dual and quad versions have
identical specifications for maximum design flexibility. Unlike most op amps, which
are specified at only one supply voltage, OPA171 op amps are specified from
+2.7V to +36V. Input signals beyond the supply rails will not cause phase reversal.

The OPA209 series of precision operational amplifiers achieves very low voltage
noise density (2.2nV/√Hz) with a supply current of only 2.5mA (max). These
amplifiers provide fast settling time to 16-bit accuracy even for 10V output
swings in precision data acquisition applications. This excellent AC performance,
combined with only 150
μ
V (max) of offset and low drift over temperature, makes
the OPA209 very suitable for fast, high-precision applications.

PGA870 functional block diagram
The PGA870 is a high-speed, fully differential, 14-bit ADC driver with a Digital
Variable Gain Amplifier (DVGA). The PGA870 offers low distortion, a wide gain
range (-11.5dB to +20dB), and very fast gain switching time, making it suitable for
fast gain control loop applications in 3G/4G radios. The PGA870 DVGA can be
used for high-speed data conversion applications that require 14-bit ADC perfor-
mance with adjustable gain on the inputs to the ADC. The PGA870 was designed
with a voltage-mode output to improve gain flatness in the pass band and elimi-
nate the need for output inductors, thereby lowering BOM costs.
Key Features
Wideband: 650MHz –3dB bandwidth
Low impedance, voltage-mode output
High linearity: OIP3 = 47dBm at 100MHz
HD2: –93dBc at 100MHz
HD3: –88dBc at 100MHz
IMD3: –99dBc at f1=90MHz, f2=100MHz
Slew rate: 2800V/µs
Wide adjustable gain range:
–11.5dB to +20dB
0.5dB gain resolution control
Fast gain switching time: 3ns
Applications
• Programmable gain IF amplifiers
CDMA/WCDMA (3G) base station

Low-power data acquisition systems
High density MRI/CAT front end
Portable instruments
The THS4521 (single), THS4522 (dual) and THS4524 (quad) are negative-rail input,
rail-to-rail output, fully differential amplifiers operating from a single +2.7 to +5V
supply. The low 1mA/channel quiescent current and power down capability to 1µA
makes it a good choice for low power applications. The output common-mode
control with low offset and drift allows for DC-coupling in high-accuracy
data acquisition systems.

THS770006 functional block diagram
The THS770006 is a low-noise, fully differential operational amplifier that
provides the high linearity and dynamic range performance required for driving
14- and 16-bit ADCs, in high IF architectures, for wireless infrastructure, test and
measurement, and defense applications. The THS770006 will support 16 bits of
full-scale (3Vp-p) precision up to 200MHz IF in order to drive high-speed ADCs
with very low distortion. The THS770006 provides the dynamic range
performance that is compatible with 16-bit high-speed signal chains, with lower
distortion and higher linearity than competing solutions. The THS770006 was
designed with a voltage-mode output to improve gain flatness in the pass band
and eliminate the need for output inductors, thereby lowering BOM costs.
Key Features
• Fully differential wideband operation:
2.4GHz small signal bandwidth
675MHz large signal bandwidth
• Low distortion: IMD3 of -107dBc at
100MHz, 2Vpp
• High linearity: OIP3 of 48dBm at
100MHz, 2Vpp
• Low voltage noise at flatband
(f >100kHz): 1.7 nV/√Hz
• Fast overdrive recovery: 7.5ns max
• Single supply +5V operation
• Low impedance, voltage-mode output
• Quiescent current: 100mA,
power-down <3mA
