AD7801BRZ
1. Low Power, Single Supply operation. This part operates
from a single 2.7 V to 5.5 V supply and consumes typically
5 mW at 3 V, making it ideal for battery powered applications.
2. The on-chip output buffer amplifier allows the output of the
DAC to swing rail to rail with a settling time of typically 1.2 ?s.
3. Internal or external reference capability.
4. High speed parallel interface.
5. Power-down capability. When powered down the DAC
consumes less than 1 ?A at 25?C.
6. Packaged in 20-lead SOIC and TSSOP packages.
AD7824BQ
The AD7824 and AD7828 are high speed, multichannel, 8-bit
ADCs with a choice of four (AD7824) or eight (AD7828) multiplexed analog inputs. A half-flash conversion technique gives a fast
conversion rate of 2.5 ?s per channel, and the parts have a built-in
track-and-hold function capable of digitizing full-scale signals of
10 kHz (157 mV/?s slew rate) on all channels. The AD7824 and
AD7828 operate from a single 5 V supply and have an analog input
range of 0 V to 5 V, using an external 5 V reference.
Microprocessor interfacing of the parts is simple, using standard
Chip Select (CS) and Read (RD) signals to initiate the conversion
and read the data from the three-state data outputs. The half-flash
conversion technique means that there is no need to generate a
clock signal for the ADC. The AD7824 and AD7828 can be
interfaced easily to most popular microprocessors.
AD810AN
The AD810 is a composite and HDTV-compatible, current
feedback, video operational amplifier, ideal for use in systems
such as multimedia, digital tape recorders, and video cameras.
The 0.1 dB flatness specification at a bandwidth of 30 MHz
(G = 2) and the differential gain and phase of 0.02% and 0.04?
(NTSC) make the AD810 ideal for any broadcast quality video
system. All these specifications are under load conditions of
150 ? (one 75 ? back terminated cable).
The AD810 is ideal for power sensitive applications such as
video cameras, offering a low power supply current of 8.0 mA
maximum. The disable feature reduces the power supply
current to only 2.1 mA, while the amplifier is not in use, to
conserve power. Furthermore, the AD810 is specified over a
power supply range of ?5 V to ?15 V.
The AD810 works well as an ADC or DAC buffer in video
systems due to its unity gain (G = 1) ?3 dB bandwidth of
80 MHz. Because the AD810 is a transimpedance amplifier, this
bandwidth can be maintained over a wide range of gains while
featuring a low noise of 2.9 nV/?Hz for wide dynamic range
applications.
AD811AN
A wideband current feedback operational amplifier, the AD811
is optimized for broadcast-quality video systems. The ?3 dB
bandwidth of 120 MHz at a gain of 2 and the differential gain
and phase of 0.01% and 0.01? (RL = 150 ?) make the AD811 an
excellent choice for all video systems. The AD811 is designed to
meet a stringent 0.1 dB gain flatness specification to a bandwidth of
35 MHz (G = 2) in addition to low differential gain and phase
errors. This performance is achieved whether driving one or two
back-terminated 75 ? cables, with a low power supply current
of 16.5 mA. Furthermore, the AD811 is specified over a power
supply range of ?4.5 V to ?18 V.
AD811JR
A wideband current feedback operational amplifier, the AD811
is optimized for broadcast-quality video systems. The ?3 dB
bandwidth of 120 MHz at a gain of 2 and the differential gain
and phase of 0.01% and 0.01? (RL = 150 ?) make the AD811 an
excellent choice for all video systems. The AD811 is designed to
meet a stringent 0.1 dB gain flatness specification to a bandwidth of
35 MHz (G = 2) in addition to low differential gain and phase
errors. This performance is achieved whether driving one or two
back-terminated 75 ? cables, with a low power supply current
of 16.5 mA. Furthermore, the AD811 is specified over a power
supply range of ?4.5 V to ?18 V.
AD817AR
The AD817 is a low cost, low power, single/dual supply, high
speed op amp which is ideally suited for a broad spectrum of
signal conditioning and data acquisition applications. This
breakthrough product also features high output current drive
capability and the ability to drive an unlimited capacitive load
while still maintaining excellent signal integrity
AD830AN
The AD830 is a wideband, differencing amplifier designed for use
at video frequencies but also useful in many other applications. It
accurately amplifies a fully differential signal at the input and
produces an output voltage referred to a user-chosen level. The
undesired common-mode signal is rejected, even at high
frequencies. High impedance inputs ease interfacing to finite
source impedances and, thus, preserve the excellent commonmode rejection. In many respects, it offers significant
improvements over discrete difference amplifier approaches, in
particular in high frequency common-mode rejection.
