The ADC122S101 is a low-power, two-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface. It is fully specified over a sample rate range of 500 kSPS to 1 MSPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept one or two input signals at inputs IN1 and IN2. The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROW- IRE, and many common DSP serial interfaces. The ADC122S101 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 4.3 mW and 13.1 mW, respec- tively. The power-down feature reduces the power consump- tion to just 0.14 µW using a +3V supply, or 0.32 µW using a +5V supply. The ADC122S101 is packaged in an 8-lead MSOP package. Operation over the industrial temperature range of −40˚C to +85˚C is guaranteed.

ADC0820 is a 8-bit high precision A/D converter with track/hold function produced by Microchip Technology. It uses a half-flash conversion technique and offers a 1.5µs conversion time and dissipates only 75mW of power. The ADC0820 has a built-in track-and-hold function and does not require an external sample-and-hold circuit. It can be used as a memory location or I/O port for easy interface with a microprocessor.

The ADC08200 is a low-power, 8-bit, monolithic analog-to-digital converter with an on-chip track-and-hold circuit. Optimized for low cost, low power, small size and ease of use, this product operates at conversion rates up to 230 MSPS while consuming just 1.05 mW per MHz of clock frequency, or 210 mW at 200 MSPS. Raising the PD pin puts the ADC08200 into a Power Down mode where it consumes 1 mW. The unique architecture achieves 7.3 Effective Bits with 50 MHz input frequency. The ADC08200 is resistant to latch-up and the outputs are short-circuit proof. The top and bottom of the ADC08200’s reference ladder are available for connections, enabling a wide range of input possibilities. The digital outputs are TTL/CMOS compatible with a separate output power supply pin to support interfacing with 3V or 2.5V logic. The digital inputs (CLK and PD) are TTL/CMOS compatible. The ADC08200 is offered in a 24-lead plastic package (TSSOP) and is specified over the industrial temperature range of −40˚C to +85˚C.
