Part Details:

16-Bit, 1 MSPS PulSAR ADC in MSOP/QFN AD7980 FEATURES APPLICATION DIAGRAM EXAMPLE 2.5V TO 5V 2.5V 16-bit resolution with no missing codes Throughput: 1 MSPS Low power dissipation: 7.0 mW @ 1 MSPS, 70 W @ 10 kSPS INL: ±0.6 LSB typical, ±1.25 LSB maximum REF VDD VIO 1.8V TO 5V 0 TO VREF SINAD: 91.25 dB @ 10 kHz SDI IN+ AD7980 SCK THD: -110 dB @ 10 kHz 3- OR 4-WIRE INTERFACE IN­ SDO (SPI, DAISY CHAIN, CS) Pseudo differential analog input range GND CNV 0 V to VREF with VREF between 2.5 V to 5.5 V 01 Any input range and easy to drive with the ADA4841 02-39 No pipeline delay 06 Figure 1. Single-supply 2.5 V operation with 1.8 V/2.5 V/3 V/5 V logic interface GENERAL DESCRIPTION Serial interface SPI-/QSPITM-/MICROWIRETM-/DSP-compatible The AD7980 is a 16-bit, successive approximation, analog-to- Daisy-chain multiple ADCs and busy indicator digital converter (ADC) that operates from a single power 10-lead MSOP and 10-lead, 3 mm × 3 mm, QFN (LFCSP), supply, VDD. It contains a low power, high speed, 16-bit same space as SOT-23 sampling ADC and a versatile serial interface port. On the CNV Wide operating temperature range: -40°C to +125°C rising edge, it samples an analog input IN+ between 0 V to REF APPLICATIONS with respect to a ground sense IN-. The reference voltage, REF, is applied externally and can be set independent of the supply Battery-powered equipment voltage, VDD. Its power scales linearly with throughput. Communications ATE The SPI-compatible serial interface also features the ability, Data acquisitions using the SDI input, to daisy-chain several ADCs on a single, Medical instruments 3-wire bus and provides an optional busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate supply VIO.
