MAX11262
14-Bit, 500ksps, +5V Unipolar Input,
SAR ADC in Tiny 10-Pin µMAX
General Description
The MAX11262 is a 14-bit, 500ksps, +5V unipolar pseu-
do-differential input SAR ADC offering excellent AC and
DC performance in a small standard package.
Benefits and Features
● High DC/AC Accuracy Improves Measurement
Quality
• 14-Bit Resolution with No Missing Codes
• 500ksps Throughput Rates Without Pipeline Delay/
Latency
This ADC typically achieves 85.4dB SNR, -102dB THD,
and ±0.2 LSB INL (typ), ±0.12 LSB DNL (typ). The
MAX11262 guarantees 14-bit no-missing codes.
• 85.4dB SNR and -102dB THD at 10kHz
• 0.1 LSB
Transition Noise
RMS
The MAX11262 communicates using an SPI-compatible
serial interface at 2.3V, 3V, 3.3V, or 5V logic.
• ±0.12 LSB DNL (typ) and ±0.2 LSB INL (typ)
● Wide Supply Range and Low Power Simplify Power-
Supply Design
The serial interface can be used to daisy-chain multiple
ADCs for multichannel applications and provides a busy
indicator option for simplified system synchronization and
timing.
• 5V Analog Supply
• 2.3V to 5V Digital Supply
• 23.5mW Power Consumption at 500ksps
• 10μA in Shutdown Mode
The MAX11262 is offered in a 10-pin, 3mm x 5mm,
