The AD7992 is a 12-bit, low power, successive approximation ADC with an I2 C-compatible interface. The part operates from a single 2.7 V to 5.5 V power supply and features a 2 µs conversion time. The part contains a 2-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11 MHz. The AD7992 provides a 2-wire serial interface compatible with I2C interfaces. The part comes in two versions, the AD7992-0 and the AD7992-1, and each version allows for at least two different I2C addresses. The AD7992-0 supports standard and fast I2C interface modes, and the AD7992-1 supports standard, fast, and high speed I2C interface modes. The AD7992 normally remains in a shutdown state while not converting, and powers up only for conversions. The conversion process can be controlled using the CONVST pin, by a command mode where conversions occur across I2C write operations, or an automatic conversion interval mode selected through software control. The AD7992 requires an external reference in the range of 1.2 V to VDD. This allows the widest dynamic input range to the ADC. On-chip limit registers can be programmed with high and low limits for the conversion result, and an open-drain, out-of-range indicator output (ALERT) becomes active when the conversion result violates the programmed high or low limits. This output can be used as an interrupt. PRODUCT HIGHLIGHTS * 2 µs conversion time and low power consumption. * I2C-compatible serial interface with pin-selectable addresses. Two AD7992 versions allow five AD7992 devices to be connected to the same serial bus. * The part features automatic shutdown while not converting to maximize power efficiency. Current consumption is 1 µA max when in shutdown mode at 3 V. * Reference can be driven up to the power supply. * Out-of-range indicator that can be software disabled or enabled. * One-shot and automatic conversion rates. * Registers store minimum and maximum conversion results. * 12-Bit ADC with Fast Conversion Time: 2 µs * Two Single-Ended Analog Input Channels * Specified for VDD of 2.7 V to 5.5 V * Low Power Consumption * Fast Throughput Rate: - 188 kSPS * Sequencer Operation * Automatic Cycle Mode https://elecena.pl/product/691248/2-channel-12-bit-adc-with-ic-compatible-interface-in-10-lead-msop 2008-07-05 https://elecena.pl/product/691248/2-channel-12-bit-adc-with-ic-compatible-interface-in-10-lead-msop 2018-03-29 https://elecena.pl/product/691248/2-channel-12-bit-adc-with-ic-compatible-interface-in-10-lead-msop 2025-01-20
