Ppm 20-Bit, ±1 Lsb Inl, Voltage Output Dac (Ad5791); Isolated, 5 Kv, Dc-To-Dc Converter (Adum6000); Isolated Sigma-Delta Modulator (Ad7401) - Analog Devices ADSP-CM419F EZ-KIT Manual

1 ppm 20-Bit, ±1 LSB INL, Voltage Output DAC (AD5791)
gage amplifiers benefit greatly from the very low noise, low input bias current, and wide bandwidth. Many systems
can take advantage of the low noise, dc precision, and rail-to-rail output swing provided by the AD8676 to maxi-
mize SNR and dynamic range.
The smaller packages and low power consumption afforded by the AD8676 allow maximum channel density or
minimum board size for space-critical equipment.
The AD8676 is specified for the extended industrial temperature range (−40°C to +125°C). The AD8676 is availa-
ble in the 8-lead MSOP, and the popular 8-lead, narrow SOIC; both of which are lead-free packages. MSOP pack-
aged devices are only available in tape and reel format.
1 ppm 20-Bit, ±1 LSB INL, Voltage Output DAC (AD5791)
The AD57911 is a single 20-bit, unbuffered voltage-output DAC that operates from a bipolar supply of up to 33 V.
The AD5791 accepts a positive reference input in the range 5 V to VDD − 2.5 V and a negative reference input in
the range VSS + 2.5 V to 0 V. The AD5791 offers a relative accuracy specification of ±1 LSB max, and operation is
guaranteed monotonic with a ±1 LSB DNL maximum specification.
The part uses a versatile 3-wire serial interface that operates at clock rates up to 35 MHz and that is compatible with
standard SPI, QSPI™, MICROWIRE™, and DSP interface standards. The part incorporates a power-on reset cir-
cuit that ensures the DAC output powers up to 0 V and in a known output impedance state and remains in this
state until a valid write to the device takes place. The part provides an output clamp feature that places the output in
a defined load state.

Isolated, 5 kV, DC-to-DC Converter (ADUM6000)

The ADuM60001 is an isolated dc-to-dc converter based on the Analog Devices, Inc., iCoupler® technology. The
dc-to-dc converter in this device provides regulated, isolated power in several combi- nations of input and output
voltages.
The Analog Devices chip scale transformer iCoupler technology transfers isolated power in this dc-to-dc converter
with up to 31% efficiency. The result is a small form factor, total isolation solution.
Higher output power levels are obtained by using the ADuM6000 to augment the power output of the ADuM5401,
ADuM5402, ADuM5403, ADuM5404, ADuM520x, and ADuM620x iCouplers with isoPower®.
isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be tak-
en during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for
board layout recommendations.

Isolated Sigma-Delta Modulator (AD7401)

The AD74011 is a second-order, sigma-delta (Σ-Δ) modulator that converts an analog input signal into a high
speed, 1-bit data stream with on-chip digital isolation based on Analog Devices, Inc., iCoupler® technology. The
