Product details
Overview
MAX153EPP+ from Maxim Integrated is a high-speed, microprocessor-compatible 8-bit analog-to-digital converter (ADC) featuring 660ns conversion time, 1Msps throughput, and 1µA power-down current with +5V single-supply operation. It integrates internal track/hold, supports unipolar/bipolar inputs, and delivers ratiometric reference capability for precision measurement in battery-constrained systems.
For engineers reviewing the MAX153EPP+ datasheet, MAX153EPP+ pinout, MAX153EPP+ application, or MAX153EPP+ equivalent, key selection considerations include burst-mode timing (200ns wake-up), µP bus interface compatibility without external logic, full-power bandwidth of 1MHz, and validated performance across –40°C to +85°C industrial temperature range.
Technical Context
The MAX153EPP+ employs a half-flash architecture with two 4-bit flash ADC sections and an internal 4-bit DAC to generate the lower 4 bits from the residue voltage-enabling 8-bit resolution at 1Msps. Its digital interface operates in RD mode (MODE = GND) or WR-RD mode (MODE = VDD), with INT and RDY outputs supporting µP wait-state control.
Power-down is activated by TTL/CMOS-low on PWRDN while CS remains high, reducing VDD current to 1µA typical; recovery requires only 200ns before acquisition begins. Ratiometric operation is enabled via independent VREF+ and VREF– inputs, with internal reference resistance of 1kΩ to 4kΩ and support for ±5V dual supplies or +5V unipolar operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - provides 256 discrete output codes for medium-precision data acquisition |
| Conversion Time | 660ns (WR-RD mode) - enables sub-microsecond sampling for real-time control loops |
| Throughput Rate | 1Msps - supports high-speed signal digitization up to 1 million samples per second |
| Power-Down Current | 1µA typical (VDD = +5V) - extends battery life in intermittent-sampling applications |
| Full-Power Bandwidth | 1MHz - maintains accuracy for input signals up to 1MHz without attenuation |
| Input Voltage Range | Unipolar: 0V to VREF+; Bipolar: ±2.5V - configurable for sensor or AC-coupled signal chains |
| Supply Voltage | +5V single supply or ±5V dual supply - simplifies power design in mixed-signal systems |
| Total Unadjusted Error | ±1 LSB - ensures end-point accuracy without system-level calibration |
Pinout & Package
MAX153EPP+ is housed in a 20-pin narrow plastic DIP (PDIP) package with 0.3-inch body width, RoHS-compliant and lead-free (+ suffix). Pin spacing is 0.1 inch, compatible with standard through-hole PCB layouts and socket-based prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Analog input | Accepts unipolar (0V to VREF+) or bipolar (±2.5V) signals; 22pF input capacitance requires ≤2.2kΩ source impedance for full accuracy |
| 2–5, 14–17 D0–D7 | Three-state data outputs | Latched, buffered 8-bit parallel output directly connectable to µP data bus; high-impedance when CS high or in power-down |
| 6 WR/RDY | Mode-shared control/status | In RD mode: open-collector READY output; in WR-RD mode: WRITE input - eliminates need for separate control lines |
| 7 MODE | Interface mode select | Low = RD mode (conversion triggered by RD); high = WR-RD mode (conversion triggered by WR) - sets timing behavior and interrupt response |
| 8 RD | Read strobe | Active-low signal enabling data read access; must be low during data capture in both interface modes |
| 9 INT | Interrupt output | Open-drain active-low signal indicating conversion completion; resets on rising edge of CS or RD |
| 10 GND | Digital ground | Reference return for digital I/O; separate from analog ground in layout-sensitive designs |
| 11 VREF– | Reference lower bound | Sets zero-code voltage; range VSS < VREF– < VREF+; draws current even in power-down unless externally switched |
| 12 VREF+ | Reference upper bound | Sets full-scale voltage; range VREF– < VREF+ < VDD; internal 1–4kΩ resistance affects reference driver requirements |
| 13 CS | Chip select | Active-low enable; must be high during power-down to prevent spurious conversions |
| 18 PWRDN | Power-down control | TTL/CMOS-low disables internal circuitry; reduces VDD current to 1µA; requires CS high to activate |
| 19 VSS | Negative supply | 0V for unipolar operation; –5V ±5% for bipolar operation - defines analog input common-mode range |
| 20 VDD | Positive supply | +5V ±5%; bypassed with 4.7µF + 0.1µF capacitors close to pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 2.7V–5.25V supply, SPI interface, no power-down pin, 1µs conversion time | Requires serial interface logic and external clock; lacks µP-bus compatibility and sub-microsecond wake-up | Select when board space is limited and SPI is already used; avoid when µP parallel bus or burst-mode timing is required |
| MAX1113ECM+ | Same manufacturer, 8-bit, 1.5Msps, but uses successive approximation (SAR), no internal T/H, 2.7V–5.25V supply | Higher speed but requires external track/hold; lower power-down current (300nA) but slower wake-up (1.5µs) | Prefer for ultra-low-power continuous sampling; choose MAX153EPP+ when internal T/H and 200ns wake-up are mandatory |
Compared with ADS7822U and MAX1113ECM+, the MAX153EPP+ uniquely combines µP-bus compatibility, internal track/hold, 660ns conversion, and 200ns wake-up - making it optimal for burst-mode, low-latency embedded control where parallel interface and rapid responsiveness are non-negotiable.

FAQ
What is the operating temperature range of the MAX153EPP+?
The MAX153EPP+ is rated for industrial operation from –40°C to +85°C, as confirmed by production testing and absolute maximum ratings in the official datasheet. This range supports deployment in automotive under-hood modules, outdoor telecom equipment, and factory automation controllers where ambient temperatures exceed commercial-grade limits. The MAX153EPP+ maintains specified accuracy and timing performance across this full span without derating.
Does the MAX153EPP+ require an external clock signal?
No, the MAX153EPP+ does not require an external clock signal. Its timing is fully self-contained using internal control circuitry, enabling direct connection to microprocessors without clock generation components. This is explicitly stated in the Features section and verified in the Functional Diagram and Timing Characteristics tables, where all timing parameters (e.g., tCWR, tCRD) are defined relative to control inputs (WR, RD, CS), not an external CLK pin.
How does the power-down mode function on the MAX153EPP+?
The MAX153EPP+ enters power-down mode when the PWRDN pin is driven low (≤0.8V) while CS is held high; this reduces VDD supply current to 1µA typical. Recovery takes less than 200ns, after which acquisition begins within 160ns. During power-down, digital outputs go high-impedance and INT becomes inactive - behavior confirmed in the Power-Down Mode section and Electrical Characteristics table under "Power-Down VDD Current".
Can the MAX153EPP+ operate with a single +5V supply in bipolar mode?
No, the MAX153EPP+ requires dual ±5V supplies for true bipolar operation (±2.5V input range), as specified in the Electrical Characteristics table under "Negative Supply Voltage (Bipolar Operation)" and confirmed in the General Description. With only +5V applied, VSS = GND, limiting input to unipolar 0V–VREF+; attempting bipolar input without –5V risks violating absolute maximum ratings on VSS and degrading accuracy.
What package type is used for the MAX153EPP+?
The MAX153EPP+ uses a 20-pin narrow-body plastic DIP (PDIP) package, designated in the Ordering Information table as "20 PDIP" with package code P20+3. The "+" suffix confirms RoHS compliance and lead-free finish. This through-hole package supports breadboarding, socket-based validation, and legacy industrial PCB assembly, distinct from SO(W) or SSOP variants like MAX153EWP+ or MAX153EAP+.
