ADA4899-1 Product details

GENERAL DESCRIPTION

The AD7986 is an 18-bit, 2 MSPS successive approximation, analog-to-digital converter (ADC). It contains a low power, high speed, 18-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and a versatile serial interface port. On the rising edge of CNV, the AD7986 samples the voltage difference between the IN+ and IN− pins. The voltages on these pins usually swing in opposite phases between 0 V and VREF. It features a very high sampling rate turbo mode (TURBO = high) and a reduced power normal mode (TURBO = low) for low power applications where the power is scaled with the throughput.



FEATURES

18-bit resolution with no missing codes

Throughput: 2 MSPS (TURBO = high), 1.5 MSPS (TURBO = low)

Low power dissipation

  15 mW at 2 MSPS, with external reference

  26 mW at 2 MSPS with internal reference

INL: ±1 LSB typical, ±2.5 LSB maximum

SNR

  95.5 dB, with on-chip reference

  97.0 dB, with external reference

4.096 V internal reference: typical drift of 10 ppm/°C

True differential analog input voltage range: ±VREF

  0 V to VREFwith VREFup to 5.0 V

  Allows use of any input range

No pipeline delay

Logic interface: 1.8 V/2.5 V/2.7 V

Serial interface: SPI/QSPI™/MICROWIRE™/DSP compatible

Ability to daisy-chain multiple ADCs with busy indicator

20-lead 4 mm × 4 mm LFCSP (QFN)



APPLICATIONS

Battery-powered equipment

Data acquisition systems

Medical instruments

Seismic data acquisition systems
