ADCS7476 General Description

The ADCS7476, ADCS7477, and ADCS7478 are low power, monolithic CMOS 12-, 10- and 8-bit analog-to-digital converters that operate at 1 MSPS. The ADCS7476/77/78 are drop-in replacements for Analog Devices' AD7476/77/78. Each device is based on a successive approximation register architecture with internal track-and-hold. The serial interface is compatible with several standards, such as SPI™, QSPI™, MICROWIRE™, and many common DSP serial interfaces.

The ADCS7476/77/78 uses the supply voltage as a reference, enabling the devices to operate with a full-scale input range of 0 to V_DD. The conversion rate is determined from the serial clock (SCLK) speed. These converters offer a shutdown mode, which can be used to trade throughput for power consumption. The ADCS7476/77/78 is operated with a single supply that can range from +2.7V to +5.25V. Normal power consumption during continuous conversion, using a +3V or +5V supply, is 2 mW or 10 mW respectively. The power down feature, which is enabled by a chip select ( ^CS) pin, reduces the power consumption to under 5 µW using a +5V supply. All three converters are available in a 6-lead, SOT-23 package and in a 6-lead LLP, both of which provide an extremely small footprint for applications where space is a critical consideration. These products are designed for operation over the automotive/extended industrial temperature range of −40°C to +125°C.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
ADCS7476AIMF	CMOS7	0	16561	0	0	954000	4	270700104
ADCS7476AIMFX	CMOS7	0	16561	0	0	954000	4	270700104

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
