14-bit 1.2MS/s SAR ADC

Features

• TSMC 40nm ULP (Ultra Low-Power Process)
• 1.62V up to 3.63V I/O Supply
• 0.9V Core Supply
• 14-bit SAR ADC
• Re-configurable for 14 / 12 / 10 / 8 bit ADC Mode
• Sampling Rate up to 1.2MS/s
• Power Scales with Sampling Rate
• 16 MUX Input Channels:
• 2 Fully-Differential Input
• 14 Pseudo-Differential Unipolar Input
• Input Signal Range: 0 to VREF
• External Reference VREF:
• 1.5V or 2.0V
• Input Capacitance: 3.6pF
• Gain Error < 1%
• Input Referred Offset < 1%
• Static Performance:
• DNL < ± 0.9 LSB (no Missing-Codes)
• INL < ± 2.0 LSB
• Outstanding Dynamic Performance:
• 74.0dB SNDR
• 12.0-bit ENOB
• Conversion and Idle Modes
• Ide Mode:
• No Power Dissipation
• No Wake-Up Time
• Ultra Low Power Dissipation:
• Only 200uA Supply Current during Conversion (from all supplies)
• Ultra Compact Die Area: <0.078mm2

Benefits

• This high-end performance is obtained with 200uA only. Total Supply Current from all supplies during conversion. In Idle mode, the IP has no Power Dissipation and it is immediately ready for new conversions, not requiring any Wake-Up time.
• To allow for application flexibility whilst offering minimum area and power dissipation, the S3ADS1M14BT40ULP IP is an ADC core that does not include voltage generation and buffering. It can readily leverage from existing references, or if required a customized solution for a bandgap and/or a reference buffer can be included.
• The S3ADS1M14BT40ULP can be cost-effectively ported across foundries and process nodes upon request.
