Product details
Overview
MAX113CAG from Maxim Integrated is a +3V, 4-channel, 8-bit analog-to-digital converter (ADC) using half-flash architecture to achieve 1.8µs conversion time (400ksps), 1µA power-down current, and ratiometric operation via internal track/hold and REF+/REF− inputs. It interfaces directly to 8-bit parallel microprocessor buses and targets battery-powered data acquisition in portable instrumentation.
For engineers reviewing the MAX113CAG datasheet, MAX113CAG pinout, MAX113CAG application, or MAX113CAG equivalent, key selection criteria include its 4-channel count, SSOP-24 package, single-supply +3.0V–+3.6V operation, 1.5mA active supply current, and guaranteed no-missing-codes performance across 0°C to +70°C.
Technical Context
The MAX113CAG implements a two-stage half-flash ADC architecture: a 4-bit flash section generates MSBs and drives an internal DAC to produce a residue voltage, which a second 4-bit flash section converts to LSBs-achieving full 8-bit resolution with only 15 comparators. Its analog multiplexer selects among four independent input channels under A0–A2 address control.
Digital interface supports two modes: read mode (MODE = 0) uses RD to initiate and latch conversion data with RDY status output; write-read mode (MODE = 1) uses WR to start conversion and INT to signal completion, enabling pipelined operation when WR and RD are tied together. Power-down (PWRDN) reduces VDD current to 1µA with <900ns wake-up latency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - delivers 256 discrete digital codes over full-scale input range |
| Conversion Time | 1.8µs - enables 400ksps sampling rate in WR-RD mode for real-time signal capture |
| Total Unadjusted Error | ≤ ±1LSB - ensures monotonic transfer function and no missing codes across temperature |
| Supply Current (Active) | 1.5mA typical at +3V - supports low-power operation in portable systems without external regulators |
| Power-Down Current | 1µA typical - reduces system standby power by >99% during burst-mode sensing intervals |
| Input Voltage Range | GND to VDD - allows direct interfacing with unbuffered sensors and rail-to-rail signal sources |
| Reference Input | Ratiometric REF+/REF− - eliminates gain error drift when reference and analog inputs share same supply |
Pinout & Package
MAX113CAG is housed in a 24-pin shrink small-outline package (SSOP) with 0.635mm pitch, JEDEC MO-153 compliant, suitable for high-density PCB layouts and automated assembly.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 21–24 | IN1–IN4, VDD, PWRDN, A0, A1 | Analog inputs (1–4), +3V supply, power-down control, and channel address LSBs for multiplexer selection |
| 5–9, 16–20 | D0–D7, CS, WR/RDY, REF+, REF− | 8-bit three-state data bus, chip-select enable, dual-function WR/status pin, and precision reference span terminals |
| 10–15 | RD, INT, GND, MODE, D3, A2 | Read strobe, interrupt flag, ground return, interface mode select, mid-byte data, and channel address MSB |
Key Features
| Feature | Design Value |
|---|---|
| Half-flash conversion architecture | Combines speed of flash with efficiency of successive approximation-achieves 8-bit accuracy in 1.8µs with minimal comparator count |
| Internal track/hold circuit | Acquires fast analog signals up to 300kHz full-power bandwidth without external sample-hold components |
| Ratiometric reference configuration | Eliminates gain error sensitivity to supply variation-ideal for sensor front-ends powered from same rail as ADC reference |
| Microprocessor-compatible interface | Latched three-state outputs and memory/I/O-mapped timing eliminate glue logic for 8-bit µP buses |
| Ultra-low power-down mode | 1µA shutdown current with sub-900ns wake-up enables energy-per-sample optimization in duty-cycled systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel, 8-bit, low-power ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX113CNG | DIP-24 package instead of SSOP-24; identical electrical specs and pinout mapping | Preferred for prototyping or through-hole assembly; larger footprint and higher thermal resistance | Select MAX113CNG for breadboarding or legacy DIP-based designs where reflow compatibility is not required |
| ADS7822U | 2.7V–5.25V supply range; SPI interface instead of parallel; 1MSPS max rate; no internal track/hold | Suited for mixed-voltage systems and space-constrained designs needing serial interface | Choose ADS7822U when board space is critical and µP has SPI but lacks 8-bit parallel bus resources |
Compared with MAX113CNG and ADS7822U, the MAX113CAG uniquely balances SSOP-24 miniaturization, parallel µP compatibility, and integrated track/hold-making it optimal for cost-sensitive, high-volume portable instruments requiring rapid analog capture without external support circuitry.

FAQ
What is the operating temperature range for the MAX113CAG?
The MAX113CAG is specified for operation from 0°C to +70°C, matching commercial-grade environmental requirements. This range is confirmed in the Ordering Information table, where MAX113CAG is explicitly listed with "0°C to +70°C" under TEMP. RANGE. The device's electrical characteristics-including total unadjusted error, conversion time, and supply current-are guaranteed across this full interval.
Does the MAX113CAG require an external clock source?
No, the MAX113CAG does not require an external clock. Its half-flash architecture and internal timing control eliminate the need for external clocking-conversion is initiated solely by digital control signals (RD or WR). This is explicitly stated in the Features list: "No External Clock Required," and verified in the Timing Characteristics section where all parameters (e.g., tCWR, tCRD) are defined relative to control signal edges, not clock cycles.
How many analog input channels does the MAX113CAG support?
The MAX113CAG supports exactly four analog input channels (IN1–IN4), as confirmed by the General Description ("The 4-channel MAX113"), Pin Configuration diagram (showing IN1–IN4 on pins 5–8), and Table 1 (Truth Table for Input Channel Selection), which lists only four valid channel combinations for MAX113 variants. The MAX117 (8-channel) is a separate part number and not applicable to MAX113CAG.
What package type is used for the MAX113CAG?
The MAX113CAG uses a 24-pin shrink small-outline package (SSOP), as documented in the Ordering Information table: "MAX113CAG → PIN-PACKAGE: 24 SSOP". This is distinct from the MAX113CNG (24 Narrow Plastic DIP) and MAX113C/D (dice), and is verified by the Pin Configurations diagram labeled "MAX113" in SSOP outline with 24 leads.
Can the MAX113CAG operate from a +3.3V supply?
Yes, the MAX113CAG operates from +3.0V to +3.6V, fully covering +3.3V. The Electrical Characteristics table specifies VDD min/max as 3.0V/3.6V, and Typical Operating Characteristics include plots at VDD = 3.3V (e.g., "CONVERSION TIME vs. SUPPLY VOLTAGE"). All key parameters-including 1.8µs conversion time and ≤±1LSB error-are guaranteed across this entire range, including +3.3V nominal operation.
