AD7472ARZ

Analog Devices Inc.
The AD7470/AD7472 are 10-bit /12-bit high speed, low power, successive-approximation ADCs. The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1.5 MSPS for the 12-bit AD7472 and up to 1.75 MSPS for the 10-bit AD7470. The parts contain a low-noise, wide bandwidth track/hold amplifier which can handleinput frequencies in excess of 20 MHz.The conversion process and data acquisition are controlledusing standard control inputs, allowing easy interfacing tomicroprocessors or DSPs. The input signal is sampled on thefalling edge of CONVST, and conversion is also initiated atthis point. BUSY goes high at the start of conversion andgoes low 531.66 ns after falling edge of CONVST (AD7472with a clock frequency of 26 MHz) to indicate that the conversionis complete. There are no pipeline delays associatedwith the parts. The conversion result is accessed via standardCS and RD signals over a high speed parallel interface.The AD7470/AD7472 use advanced design techniques toachieve very low power dissipation at high throughput rates. With3 V supplies and 1.5 MSPS throughput rates, the AD7470typically consumes, on average, just 1.1 mA. With 5 V suppliesand 1.75 MSPS, the average current consumption is typically1.6 mA. The part also offers flexible power/throughput ratemanagement. Operating the AD7470 with 3 V supplies and500 kSPS throughput reduces the current consumption to 713 μA.At 5 V supplies and 500 kSPS, the part consumes 944 μA.It is also possible to operate the parts in an auto sleep mode,where the part wakes up to do a conversion and automaticallyenters sleep mode at the end of conversion. This method allowsvery low power dissipation numbers at lower throughput rates.In this mode, the AD7472 can be operated with 3 V supplies at100 kSPS, and consume an average current of just 124 μA. At5 V supplies and 100 kSPS, the average current consumption is171 μA.The analog input range for the part is 0 V to REF IN. The 2.5 Vreference is applied externally to the REF IN pin. The conversionrate is determined by the externally-applied clock.ol { margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:25px; padding-top:0px; padding-right:0px; padding-bottom:10px; padding-left:0px;}li { padding-top:0px; padding-right:0px; padding-bottom:5px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px;}Product HighlightsHigh Throughput with Low Power Consumption. TheAD7470 offers 1.75 MSPS throughput and the AD7472offers 1.5 MSPS throughput rates with 4 mW powerconsumption.Flexible Power/Throughput Rate Management.

AD7820KRZ

Analog Devices Inc.
The AD7820 is a high speed, microprocessor-compatible 8-bit ADC which uses a half-flash conversion technique to achieve a conversion time of 1.36 µs. The converter has a 0 V to +5 V analog input voltage range with a single +5 V supply.The half-flash technique consists of 31 comparators, a most significant 4-bit ADC and a least significant 4-bit ADC. The input to the AD7820 is tracked and held by the input sampling circuitry, eliminating the need for an external sample-and-hold for signals with slew rates less than 100 mV/µs.The part is designed for ease of microprocessor interface with the AD7820 appearing as a memory location or I/O port without the need for external interfacing logic. All digital outputs use latched, three-state output buffer circuitry to allow direct connection to a microprocessor data bus or system input port. A non-three state overflow output is also provided to allow cascading of devices to give higher resolution.

AD7845KRZ

Analog Devices Inc.
The AD7845 is the industry's first 4-quadrant multiplying D/A converter with an on-chip amplifier. It is fabricated on the LC2MOS process, which allows precision linear components and digital circuitry to be implemented on the same chip.The 12 data inputs drive latches which are controlled by standard CS and WR signals, making microprocessor interfacing simple. For stand-alone operation, the CS and WR inputs can be tied to ground, making all latches transparent. All digital inputs are TTL and 5 V CMOS compatible.The output amplifier can supply ±10 V into a 2k(ohm) load. It is internally compensated, and its input offset voltage is low due to laser trimming at wafer level. For normal operation, RFB is tied to VOUT, but the user may alternatively choose RA, RB or RC to scale the output voltage range.

OP270EZ

Analog Devices Inc.
The OP270 is a high performance, monolithic, dual operational amplifier with exceptionally low voltage noise density (5 nV/√Hz maximum at 1 kHz). It offers comparable performance to the industry-standard OP27 from Analog Devices, Inc. The OP270 features an input offset voltage of less than 75 μV and an offset drift of less than 1 μV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP270 is more than 1,500,000 into a 10 kΩ load, ensuring excellent gain accuracy and linearity, even in high gain applications. The input bias current is less than 20 nA, which reduces errors due to signalsource resistance. With a common-mode rejection (CMR) of greater than 106 dB and a power supply rejection ratio (PSRR) of less than 3.2 μV/V, the OP270 significantly reduces errors due to ground noise and power supply fluctuations. The power consumption of the dual OP270 is one-third less than two OP27 devices, a significant advantage for power conscious applications. The OP270 is unity-gain stable with a gain bandwidth product of 5 MHz and a slew rate of 2.4 V/μs.The OP270 offers excellent amplifier matching, which is important for applications such as multiple gain blocks, low noise instrumentation amplifiers, dual buffers, and low noise active filters.The OP270 conforms to the industry-standard 8-lead CERDIP and PDIP pinouts. For higher speed applications, the ADA4004-2 or the AD8676 are recommended. For a quad op amp, see the OP470 data sheet.
