Product details
Overview
MCP47FEB11A2T-E/ST from Microchip Technology is a single-channel, 10-bit buffered voltage-output DAC with nonvolatile EEPROM, I²C interface, rail-to-rail output, and selectable reference sources (VDD, external VREF, or internal 1.22 V band gap). It delivers 6 µs typical settling time, supports 1.8–5.5 V operation, and is qualified for automotive-grade extended temperature range (–40°C to +125°C). Used in precision sensor calibration and motor control feedback loops where power-on repeatability and low drift are critical.
For engineers reviewing the MCP47FEB11A2T-E/ST datasheet, MCP47FEB11A2T-E/ST pinout, MCP47FEB11A2T-E/ST application, or MCP47FEB11A2T-E/ST equivalent, key selection criteria include guaranteed monotonicity (±0.4 LSb INL), nonvolatile POR/BOR register recall, programmable gain (1x/2x), and High-Speed I²C support up to 3.4 Mbps - all in an 8-lead TSSOP package with AEC-Q200 alignment.
Technical Context
The MCP47FEB11A2T-E/ST implements a resistor ladder architecture with buffered op-amp output stage, enabling rail-to-rail voltage generation across its full 10-bit resolution (1024 steps). Its nonvolatile memory stores DAC output value, reference selection (VRxB:VRxA), gain bit (G), power-down configuration (PD1:PD0), and slave address - all retained after reset or power cycle.
I²C communication supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes with four fixed slave addresses or full 7-bit user-programmable addressing. The LAT0/HVC pin enables WiperLock™ write protection via high-voltage command sequence, preventing accidental EEPROM writes during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit (1024 steps); guarantees monotonic output with ±0.4 LSb integral nonlinearity over full code range. |
| Settling Time | 6 µs typical to ±1/2 LSb; enables fast closed-loop response in motor control and real-time trimming applications. |
| Reference Options | VDD, external VREF (buffered/unbuffered), or internal 1.22 V band gap; allows flexible accuracy vs. power trade-offs. |
| Output Gain | Selectable 1x or 2x; 2x mode requires VREF ≤ VDD/2 when using external reference - critical for headroom planning. |
| Power Consumption | 180 µA typical active current (single channel); 650 nA typical power-down current - suitable for battery-powered instrumentation. |
| Temperature Range | –40°C to +125°C; qualified per AEC-Q200 requirements for automotive under-hood and industrial harsh environments. |
| I²C Speed | Up to 3.4 Mbps High-Speed mode; supports high-throughput configuration updates in multi-DAC systems. |
Pinout & Package
Package: 8-lead TSSOP (3.0 mm × 4.4 mm, 0.65 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT0 | Analog output | Rail-to-rail buffered voltage output; drives ≥5 kΩ load with <0.04 V headroom from rails. |
| 2 - VREF0 | Reference input | Accepts external reference (buffered or unbuffered); sets full-scale output when selected as reference source. |
| 3 - NC | No connect | Internally unused; must be left floating or tied to ground per layout guidelines. |
| 4 - SCL | I²C clock | Active-low Schmitt-trigger input; supports 3.4 MHz High-Speed mode with 10 pF pin capacitance. |
| 5 - LAT0/HVC | Latency / High-voltage control | Dual-function pin: enables WiperLock™ EEPROM write protection when driven to ≥9.0 V (VIHHEN). |
| 6 - VSS | Ground | Analog/digital common reference; separate return path required for noise-sensitive analog circuits. |
| 7 - SDA | I²C data | Open-drain bidirectional bus line; supports standard pull-up to VDD or level-shifted supply. |
| 8 - VDD | Supply voltage | 1.8–5.5 V operation; powers digital core, reference circuitry, and output amplifier - no separate AVDD required. |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile DAC register recall | Auto-recalls last-saved output value on power-on or brown-out reset - eliminates boot-time calibration overhead. |
| Programmable reference and gain | User-configurable VRxB:VRxA and G bits stored in EEPROM - enables field-adjustable full-scale range without firmware update. |
| WiperLock™ write protection | Hardware-enforced EEPROM lock via LAT0/HVC high-voltage command - prevents unintended register changes in deployed systems. |
| Low-power power-down modes | Selectable 100 kΩ or 1 kΩ VOUT pull-down resistors in PD mode - balances leakage control vs. wake-up speed. |
| Extended temperature operation | Specified performance from –40°C to +125°C with <15 ppm/°C VOUT tempco - meets automotive and industrial reliability standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP47FEB12-E/ST | Dual-channel 10-bit DAC in same TSSOP-8 package; shares identical EEPROM, I²C, and reference architecture. | Supports two independent analog outputs - suitable for differential signaling or dual-sensor systems. | Select when needing simultaneous, synchronized outputs; requires minor firmware adaptation for dual-register access. |
| AD5621BRMZ-REEL7 | Single 10-bit DAC with SPI interface, no EEPROM, 2.7–5.5 V supply, ±0.5 LSB INL, –40°C to +105°C rating. | Lacks nonvolatile memory and I²C compatibility; requires external controller to reload settings after power loss. | Choose for cost-sensitive, SPI-based designs where EEPROM persistence is not required and temperature range is less demanding. |
Compared with MCP47FEB12-E/ST, the MCP47FEB11A2T-E/ST saves board space and cost in single-output systems; versus AD5621BRMZ-REEL7, it provides guaranteed power-on repeatability and I²C integration at the expense of SPI compatibility and slightly higher unit cost.

FAQ
What is the maximum I²C clock frequency supported by the MCP47FEB11A2T-E/ST?
The MCP47FEB11A2T-E/ST supports High-Speed I²C mode up to 3.4 Mbps, in addition to Standard (100 kHz) and Fast (400 kHz) modes. This capability enables rapid register updates in multi-DAC configurations and reduces configuration latency in time-critical applications. The device maintains full functionality across all three speed modes without requiring hardware reconfiguration.
Does the MCP47FEB11A2T-E/ST require an external reference voltage to operate?
No, the MCP47FEB11A2T-E/ST does not require an external reference voltage. It offers three internal reference options: the device's VDD supply, an internal 1.22 V band gap, or an external voltage applied to the VREF0 pin. When using the internal band gap, the output gain is automatically set to 2x, yielding a nominal 2.44 V full-scale output - eliminating the need for external precision references in many applications.
How does the WiperLock™ feature protect EEPROM registers in the MCP47FEB11A2T-E/ST?
The WiperLock™ feature in the MCP47FEB11A2T-E/ST uses the LAT0/HVC pin to enforce hardware-level EEPROM write protection. Writing to nonvolatile registers requires applying ≥9.0 V to this pin to enter high-voltage command mode - a deliberate, non-standard logic level that prevents accidental writes during normal I²C operation. Once enabled, only authenticated high-voltage sequences can modify EEPROM contents, ensuring configuration integrity in deployed systems.
What is the guaranteed integral nonlinearity (INL) specification for the MCP47FEB11A2T-E/ST across temperature?
The MCP47FEB11A2T-E/ST guarantees ±0.4 LSb integral nonlinearity over the full –40°C to +125°C operating range when configured with VRxB:VRxA = '10' (external unbuffered reference) and G = '0'. This specification ensures monotonic behavior and predictable transfer function accuracy in closed-loop systems where linearity directly impacts control stability and measurement fidelity.
Can the MCP47FEB11A2T-E/ST operate from a 1.8 V supply, and what performance trade-offs apply?
Yes, the MCP47FEB11A2T-E/ST operates from 1.8 V to 5.5 V. At 1.8 V, analog specifications are reduced: full-scale error increases to ±70 LSb (vs. ±18 LSb at 5.5 V), and INL degrades to ±1.5 LSb. However, digital interface functionality, EEPROM operation, and basic DAC functionality remain fully specified - making it viable for ultra-low-power applications where absolute precision is secondary to energy efficiency.
