The AD7949BCPZRL7 is a 14-bit, 8-channel, 250 kSPS SAR ADC from Analog Devices. It integrates an 8-channel multiplexer, a track-and-hold amplifier, and a successive approximation ADC in a single 20-lead LFCSP package. The device supports unipolar single-ended, differential, and pseudobipolar input configurations.
Key specifications: The ADC achieves typical INL of ±0.5 LSB and DNL of ±0.25 LSB. It provides a SINAD of 85 dB and THD of -100 dB at 20 kHz. The analog input range is 0 V to VREF, with VREF up to VDD. The device includes an internal temperature sensor and a channel sequencer.
Operating from a single 2.3V to 5.5V supply, the AD7949 consumes only 2.9 mW at 2.5V/200 kSPS and 10.8 mW at 5V/250 kSPS. The standby current is 50 nA. The serial interface is compatible with SPI, MICROWIRE, QSPI, and DSP. The device is specified over the -40°C to 85°C temperature range.
Housed in a 20-lead 4 mm × 4 mm LFCSP package, the AD7949 is suitable for space-constrained designs. Typical applications include multichannel system monitoring, battery-powered equipment, medical instruments, and data acquisition systems.
