Product details
Overview
AD7476AYKS-REEL7 from Analog Devices is a 12-bit, 1 MSPS successive-approximation ADC in a 6-lead SC70 package, operating from 2.35 V to 5.25 V supply. It delivers 71 dB SNR at 100 kHz input, features no pipeline delay, and uses internal VDD-referenced conversion for 0 V to VDD analog input range-ideal for space-constrained battery-powered data acquisition.
For engineers reviewing the AD7476AYKS-REEL7 datasheet, AD7476AYKS-REEL7 pinout, AD7476AYKS-REEL7 application, or AD7476AYKS-REEL7 equivalent, key selection factors include its 12-bit resolution with ±1.5 LSB INL, SC70 footprint compatibility, SPI/QSPI/MICROWIRE interface timing, and 1 µA standby current for ultra-low-power embedded sensing.
Technical Context
The AD7476AYKS-REEL7 implements a standard SAR architecture with track-and-hold sampling controlled by CS falling edge, enabling precise timing control without latency. Conversion is fully synchronous to SCLK, requiring exactly 16 clock cycles per result, with no pipelining or inherent delay between sample initiation and data availability.
Its reference is derived directly from VDD, eliminating external reference components and simplifying layout while maintaining full-scale range scalability. Input bandwidth supports >13 MHz signals, and digital I/Os are compatible with 3 V and 5 V logic families across the specified supply range.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822UID | 12-bit, 200 kSPS, 8-lead SOIC; requires external reference; 2.7–5.25 V supply | Lower throughput and larger package; suited for cost-sensitive industrial controls where speed is secondary | Select when board space is not constrained and external reference is already present in system |
| MAX1116EKA+T | 12-bit, 1 MSPS, 6-lead SOT23; internal reference; 2.7–3.6 V only; 1.5 µA standby | Narrower supply range limits use to 3 V systems; identical SC70 footprint but different pinout | Consider only for 3 V-only designs requiring pin-compatible replacement with verified layout adaptation |
Compared with ADS7822UID and MAX1116EKA+T, the AD7476AYKS-REEL7 uniquely combines 1 MSPS speed, 2.35–5.25 V operation, and true SC70 pin compatibility-making it optimal for next-generation miniaturized, multi-rail sensor nodes requiring no redesign.

FAQ
What is the maximum sampling rate supported by the AD7476AYKS-REEL7?
The AD7476AYKS-REEL7 supports a maximum throughput rate of 1 MSPS under specified conditions (VDD = 2.35 V to 5.25 V, fSCLK = 20 MHz). Its conversion time is fixed at 16 SCLK cycles, so actual achievable rate depends on SCLK frequency-e.g., 12.5 MHz SCLK yields 781 kSPS. The device guarantees 1 MSPS performance across its full temperature and supply range.
Does the AD7476AYKS-REEL7 require an external voltage reference?
No, the AD7476AYKS-REEL7 uses an internal reference derived from VDD, providing a 0 V to VDD analog input range. This eliminates the need for external reference components, simplifying design and reducing bill-of-materials cost. Reference accuracy tracks VDD tolerance, so system-level gain calibration may be required if VDD regulation exceeds ±1%.
What is the meaning of "Y" in the AD7476AYKS-REEL7 part number?
The "Y" denotes the Y-grade temperature rating, specifying operation from –40°C to +125°C. This grade is qualified for automotive and extended industrial applications. The AD7476AYKS-REEL7 also meets AEC-Q100 stress test requirements for automotive use, as confirmed in the official Analog Devices ordering guide and Rev. G datasheet.
How does the AD7476AYKS-REEL7 handle power-down mode?
The AD7476AYKS-REEL7 enters full power-down mode when CS remains high and no SCLK activity occurs for >100 ns. In this state, current consumption drops to 1 µA maximum (typically 50 nA), and the SDATA pin enters high-impedance. Wake-up time is 1 µs maximum, allowing rapid resumption of sampling without external reset.
Is the AD7476AYKS-REEL7 pin-compatible with other members of the AD7476A/AD7477A/AD7478A family?
Yes-the AD7476AYKS-REEL7 shares identical 6-lead SC70 pinout and interface timing with AD7477A and AD7478A variants. All three devices use the same CS/SCLK/SDATA protocol and VDD/GND/VIN connections. However, output data format differs: AD7476AYKS-REEL7 outputs 12-bit results with four leading zeros, while AD7477A and AD7478A append trailing zeros to maintain 16-bit frame length.
