Product details
Overview
ADCMP380-1ACBZ-RL7 from Analog Devices is an ultralow power voltage comparator with integrated 1 V precision reference, open-drain output, 92 nA typical supply current, and 23 μs typical propagation delay. It operates from 2 V to 5.5 V supply and monitors low-voltage nodes down to 0.5 V in battery-constrained systems such as energy harvesting sensors.
For engineers reviewing the ADCMP380-1ACBZ-RL7 datasheet, ADCMP380-1ACBZ-RL7 pinout, ADCMP380-1ACBZ-RL7 application, or ADCMP380-1ACBZ-RL7 equivalent, key selection criteria include reference accuracy (±1.6% over −40°C to +85°C), UVLO thresholds (1.65 V fall / 1.95 V rise), input leakage (≤8.5 nA), EN input timing (0.65 μs enable delay), and WLCSP package compatibility for space-limited PCB layouts.
Technical Context
The ADCMP380-1ACBZ-RL7 integrates a trimmed 1 V bandgap reference with ±1.6% accuracy across −40°C to +85°C and features internal hysteresis (10.3 mV) to suppress noise-induced oscillation at the switching threshold. Its comparator core uses rail-to-rail input operation with 4–32 nA average input current depending on VCC and VIN.
It implements undervoltage lockout (UVLO) that forces OUT low when VCC drops below 1.65 V (falling) or rises above 1.95 V (rising), ensuring clean startup and brownout behavior. The EN pin includes a 0.6 MΩ internal pull-up and on-chip debouncing, enabling reliable push-button wake-up without external RC networks.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultralow power comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7031DBVR | 350 nA ICC (typ), no internal reference, requires external 1 V source | Lacks integrated reference; needs additional components for same functionality | Choose if external reference already exists and higher speed (15 μs) is required |
| MAX9060AXK+T | 300 nA ICC (typ), 0.6 V reference, ±2.5% accuracy over temperature | Lower reference voltage and reduced accuracy limit low-VIN monitoring resolution | Choose for sub-0.6 V threshold detection where ±2.5% tolerance is acceptable |
Compared with TLV7031DBVR and MAX9060AXK+T, ADCMP380-1ACBZ-RL7 delivers superior reference integration (1 V ±1.6%), lowest ICC (92 nA), and guaranteed UVLO behavior-making it optimal for self-contained, long-life battery monitoring where component count and leakage budget are critical.

FAQ
What is the reference voltage accuracy of ADCMP380-1ACBZ-RL7 over temperature?
The ADCMP380-1ACBZ-RL7 features a factory-trimmed 1 V internal reference with ±1.6% accuracy across the full −40°C to +85°C operating range. This specification is guaranteed in production testing and applies to all units shipped under this part number, enabling precise low-voltage monitoring without external calibration.
Does ADCMP380-1ACBZ-RL7 require an external pull-up resistor on the OUT pin?
Yes, ADCMP380-1ACBZ-RL7 has an open-drain output and requires an external pull-up resistor to VCC or another logic rail. The datasheet specifies valid sink performance up to 6.5 mA at VCC > 4.25 V, and the output voltage low is guaranteed ≤0.4 V under those conditions. No internal pull-up is present on the OUT pin.
How does the EN pin behave when left unconnected?
When left unconnected, the EN pin of ADCMP380-1ACBZ-RL7 remains high due to its internal 0.6 MΩ pull-up resistor, enabling normal comparator operation. The device asserts OUT low only when EN is actively driven below 0.4 V, making it inherently safe for default-enable configurations without external biasing.
Can ADCMP380-1ACBZ-RL7 operate below 2 V supply?
No-ADCMP380-1ACBZ-RL7 is specified for 2 V to 5.5 V operation. Below 2 V, functional behavior is not guaranteed: the UVLO circuit forces OUT low starting at VCC = 1.65 V (falling), and reference accuracy degrades outside the rated range. Operation below 2 V may result in invalid output states or increased propagation delay.
What is the maximum sink current supported by ADCMP380-1ACBZ-RL7 at 3.3 V supply?
At VCC = 3.3 V, ADCMP380-1ACBZ-RL7 guarantees VOUT_OL ≤ 0.4 V for sink currents up to 6 mA, per the "VCC > 2.5 V, ISINK = 6 mA" test condition in the datasheet. This allows direct interfacing with standard 3.3 V logic inputs and microcontroller GPIOs configured as active-low interrupt lines.
