General Description

The ADC088S022 is a low-power, eight-channel CMOS 8-bit analog-to-digital converter specified for conversion throughput rates of 50 ksps to 200 ksps. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept up to eight input signals at inputs IN0 through IN7.

The output serial data is straight binary and is compatible with several standards, such as SPI, QSPI ™, MICROWIRE ™, and many common DSP serial interfaces.

The ADC088S022 may be operated with independent analog and digital supplies. The analog supply (V_A) can range from +2.7V to +5.25V, and the digital supply (V_D) can range from +2.7V to V_A. Normal power consumption using a +3V or +5V supply is 0.9 mW and 5.5 mW, respectively. The power-down feature reduces the power consumption to 0.03 µW using a +3V supply and 0.15 µW using a +5V supply.

The ADC088S022 is packaged in a 16-lead TSSOP package. Operation over the extended industrial temperature range of −40°C to +105°C is guaranteed.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
ADC088S022CIMT	CMOS7	0	18406	0	0	1089000	4	309006723
ADC088S022CIMTX	CMOS7	0	18406	0	0	1089000	4	309006723

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.
