Product details
Overview
AD7810YRMZ-REEL7 from Analog Devices is a 10-bit successive approximation ADC with 2.3 µs conversion time, pseudo-differential analog input (VIN+, VIN–), and microcontroller-compatible 3-wire serial interface (CONVST, SCLK, DOUT). It operates from a single 2.7 V to 5.5 V supply, features inherent track-and-hold, and supports automatic power-down mode - enabling ultra-low-power operation in battery-powered portable instrumentation.
For engineers reviewing the AD7810YRMZ-REEL7 datasheet, AD7810YRMZ-REEL7 pinout, AD7810YRMZ-REEL7 application, or AD7810YRMZ-REEL7 equivalent, key selection considerations include its 10-bit resolution with ±1 LSB relative accuracy, –40°C to +105°C industrial temperature range, microSOIC-8 package footprint, and support for both high-speed (Mode 1) and auto power-down (Mode 2) operation modes.
Technical Context
The AD7810YRMZ-REEL7 implements a charge redistribution DAC-based SAR architecture with internal oscillator and comparator. Its pseudo-differential input structure allows offset cancellation by applying system offset to VIN–, provided VIN– variation stays within ±½ LSB during conversion.
It supports two distinct operating modes: Mode 1 maintains continuous power for throughput up to 350 kSPS (limited by microcontroller SCLK speed), while Mode 2 uses CONVST edge detection to enable automatic wake-up and power-down - achieving as low as 27 µW at 1 kSPS and 270 µW at 10 kSPS with guaranteed 1.5 µs power-up time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit straight binary output; LSB = VREF/1024, enabling precise digitization of signals up to 1024 discrete levels. |
| Conversion Time | 2.3 µs maximum in high-speed Mode 1; defines minimum inter-conversion interval for sustained sampling. |
| Supply Range | 2.7 V to 5.5 V single supply; permits direct integration with 3.3 V or 5 V logic systems without level-shifting. |
| Relative Accuracy | ±1 LSB max over –40°C to +105°C; ensures monotonicity and no missing codes across full temperature range. |
| Power Dissipation | 2.7 mW at 100 kSPS (VDD = 5 V); drops to 270 µW at 10 kSPS using automatic power-down mode. |
| Analog Input Range | 0 V to VREF; VREF may be tied to VDD, eliminating need for external reference in many applications. |
| Reference Range | VREF supports 1.2 V to VDD; enables flexible scaling for low-voltage sensor interfaces. |
Pinout & Package
AD7810YRMZ-REEL7 is housed in an 8-lead microSOIC package (RM-8), 3.0 mm × 3.0 mm body, 0.65 mm lead pitch, gull-wing leads. RoHS-compliant, tape-and-reel packaging (REEL7 = 1000-piece reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CONVST | Convert Start / Serial Enable | Falling edge initiates conversion and places track-and-hold in hold mode; rising edge enables serial port - used for chip select in multi-device buses. |
| 2 - VIN+ | Pseudo-Differential Positive Input | Primary analog signal input; sampled against VIN–; supports unipolar 0 V to VREF range when VIN– = AGND. |
| 3 - VIN– | Pseudo-Differential Negative Input | Reference node for offset cancellation; must remain stable within ±½ LSB during conversion to avoid code errors. |
| 4 - GND | Analog/Digital Ground | Common return for analog and digital circuitry; requires low-impedance connection to minimize noise coupling. |
| 5 - VREF | Reference Voltage Input | Defines full-scale range; accepts 1.2 V to VDD; can be connected directly to VDD to simplify BOM. |
| 6 - DOUT | Serial Data Output | 3-state CMOS output; shifts out 10-bit result MSB-first on rising SCLK edges after CONVST rising edge. |
| 7 - SCLK | Serial Clock Input | Asynchronous clock input; controls data timing; compatible with SPI/QSPI/PIC16C protocols (SCLK inversion required for 8051). |
| 8 - VDD | Positive Supply | 2.7 V to 5.5 V single supply; powers analog core, digital logic, and internal oscillator. |
Key Features
| Feature | Design Value |
|---|---|
| Inherent Track-and-Hold | Eliminates need for external sample-and-hold circuitry; acquisition time ≤100 ns ensures fast settling after step input changes. |
| Microcontroller-Compatible Serial Interface | 3-wire (CONVST/SCLK/DOUT), no glue logic required; supports PIC16C, QSPI, and SPI controllers with minimal firmware overhead. |
| Automatic Power-Down Mode | Reduces average current to 1 µA (VDD = 5 V) between conversions; enables battery life extension in intermittent-sampling applications. |
| Industrial Temperature Range | Specified from –40°C to +105°C; validated for use in harsh environments including automotive under-hood and industrial control cabinets. |
| Pseudo-Differential Input Architecture | Enables common-mode offset rejection by applying system-level offset to VIN–, improving measurement accuracy in noisy sensor front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 12-bit resolution, 2.5 µs conversion, SPI-only interface (no CONVST enable), 2.7–5.25 V supply. | Higher resolution but no automatic power-down; requires external reference for full-scale accuracy. | Choose ADS7822U when 12-bit precision is mandatory and system power budget allows ~3.5 mW continuous draw. |
| MAX11100ASA+ | 10-bit, 1.5 µs conversion, internal reference (1.2 V), SPI interface, 2.7–3.6 V only. | Fixed reference limits input range flexibility; narrower supply range excludes 5 V systems. | Choose MAX11100ASA+ for space-constrained 3.3 V designs where internal reference simplifies layout and eliminates VREF routing. |
Compared with ADS7822U and MAX11100ASA+, AD7810YRMZ-REEL7 uniquely balances 10-bit accuracy, ultra-low standby current (1 µA), wide 2.7–5.5 V operation, and VREF-to-VDD flexibility - making it optimal for cost-sensitive, battery-operated industrial instruments requiring guaranteed performance across extended temperature.

FAQ
What is the maximum sampling rate achievable with AD7810YRMZ-REEL7?
The AD7810YRMZ-REEL7 achieves a maximum throughput rate of 350 kSPS under test conditions (fSAMPLE = 350 kHz, fIN = 30 kHz), limited by its 2.3 µs conversion time and microcontroller serial interface speed. In practice, sustained rates depend on SCLK frequency and host processor overhead; typical implementations achieve 100–250 kSPS with optimized SPI firmware. The part does not specify a minimum SCLK period, but timing parameters require t3/t4 ≥25 ns (VDD = 5 V).
Does AD7810YRMZ-REEL7 require an external reference voltage?
No, AD7810YRMZ-REEL7 does not require an external reference. Its VREF pin accepts 1.2 V to VDD, and connecting VREF directly to VDD establishes a 0 V to VDD analog input range - eliminating external reference components. This configuration is fully specified and maintains ±1 LSB relative accuracy across –40°C to +105°C, simplifying design and reducing BOM cost.
How does the automatic power-down mode work in AD7810YRMZ-REEL7?
In AD7810YRMZ-REEL7 automatic power-down mode (Mode 2), the device powers down immediately after conversion completion when CONVST remains low. A rising edge on CONVST wakes it up (1.5 µs power-up time), and the subsequent falling edge starts conversion. This sequence reduces average power to 27 µW at 1 kSPS and 270 µW at 10 kSPS - ideal for battery-powered applications with intermittent sampling requirements.
Can AD7810YRMZ-REEL7 interface directly with an 8051 microcontroller?
Yes, AD7810YRMZ-REEL7 can interface with an 8051 microcontroller, but the SCLK signal must be inverted because the AD7810YRMZ-REEL7 expects data valid on rising SCLK edges, whereas standard 8051 SPI peripherals drive data on falling edges. This inversion can be implemented using a single logic gate or software-controlled GPIO toggle synchronized to the 8051's shift clock.
What is the meaning of "pseudo-differential" input in AD7810YRMZ-REEL7?
The pseudo-differential input of AD7810YRMZ-REEL7 means VIN+ is the active signal input while VIN– serves as a user-defined reference node - not a true differential pair with matched gain. During conversion, the sampling capacitor connects to VIN–, allowing system-level offsets (e.g., 0.5 V) applied to VIN– to shift the effective input range. However, VIN– must remain stable within ±½ LSB during conversion; otherwise, code errors occur.
