1 / 44 page  ADC101C021, ADC101C027 www.ti.com SNAS446D – FEBRUARY 2008 – REVISED FEBRUARY 2013 ADC101C021/ADC101C027 I2C-Compatible, 10-Bit Analog-to-Digital Converter (ADC) with Alert Function Check for Samples: ADC101C021, ADC101C027 1 FEATURES DESCRIPTION The ADC101C021 is a low-power, monolithic, 10-bit, 23 • I2C-Compatible 2-wire Interface which analog-to-digital converter (ADC) that operates from a supports standard (100kHz), fast (400kHz), and +2.7 to 5.5V supply. The converter is based on a high speed (3.4MHz) modes successive approximation register architecture with • Extended power supply range (+2.7V to +5.5V) an internal track-and-hold circuit that can handle input frequencies up to 11MHz. The ADC101C021 • Up to nine pin-selectable chip addresses operates from a single supply which also serves as (VSSOP-8 only) the reference. The device features an I2C-compatible • Out-of-range Alert Function serial interface that operates in all three speed • Automatic Power-down mode while not modes, including high speed mode (3.4MHz). converting The ADC's Alert feature provides an interrupt that is • Very small SOT-6 and VSSOP-8 packages activated when the analog input violates a • ±8kV HBM ESD protection (SDA, SCL) programmable upper or lower limit value. The device features an automatic conversion mode, which frees up the controller and I2C interface. In this mode, the APPLICATIONS ADC continuously monitors the analog input for an • System Monitoring "out-of-range" condition and provides an interrupt if • Peak Detection the measured voltage goes out-of-range. • Portable Instruments The ADC101C021 comes in two packages: a small • Medical Instruments SOT-6 package with an alert output, and an VSSOP- 8 package with an alert output and two address • Test Equipment selection inputs. The ADC101C027 comes in a small SOT-6 package with an address selection input. The KEY SPECIFICATIONS ADC101C027 provides three pin-selectable • Resolution 10 bits; no missing codes addresses while the VSSOP-8 version of the ADC101C021 provides nine pin-selectable • Conversion Time 1µs (typ) addresses. Pin-compatible alternatives to the SOT-6 • INL & DNL ±0.5 LSB (max) options are available with additional address options. • Throughput Rate 188.9 kSPS (max) Normal power consumption using a +3V or +5V • Power Consumption (at 22kSPS) supply is 0.26mW or 0.78mW, respectively. The – 3V Supply 0.26 mW (typ) automatic power-down feature reduces the power consumption to less than 1µW while not converting. – 5V Supply 0.78 mW (typ) Operation over the industrial temperature range of −40°C to +105°C is guaranteed. Their low power consumption and small packages make this family of ADCs an excellent choice for use in battery operated equipment. The ADC101C021 and ADC101C027 are part of a family of pin-compatible ADCs that also provide 12 and 8 bit resolution. For 12-bit ADCs see the ADC121C021 and ADC121C027. For 8-bit ADCs see the ADC081C021 and ADC081C027. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 I2C is a registered trademark of Phillips Corporation. 3 All other trademarks are the property of their respective owners.
