Analog Devices Inc./Maxim Integrated MAX1188CCUP+T

Overview

MAX1188CCUP+T from Maxim Integrated is a 16-bit, 135ksps successive-approximation ADC with ±10V bipolar analog input range, single +4.75V to +5.25V analog supply, and byte-wide parallel interface - designed for precision industrial data acquisition where high DC accuracy (±2 LSB INL) and low THD (–100 dB) are critical.

For engineers reviewing the MAX1188CCUP+T datasheet, MAX1188CCUP+T pinout, MAX1188CCUP+T application, or MAX1188CCUP+T equivalent, this page delivers verified specifications, validated TSSOP-20 pin mapping, confirmed power-down behavior (0.5 µA shutdown current), and two field-tested alternative ADCs for ±10V bipolar sampling systems.

Technical Context

The MAX1188CCUP+T implements a SAR architecture with integrated track-and-hold and factory-trimmed internal +4.096V reference. Its input scaler enables true ±10V operation from a single +5V analog rail while maintaining 16-bit resolution and monotonicity (±1 LSB DNL).

Conversion timing is fully self-clocked: acquisition completes in 2 µs, conversion finishes in 4.7 µs max, and EOC asserts within defined setup/hold windows relative to CS and R/C. Power management is controlled via R/C state at the second CS falling edge - selecting either standby mode (3.7 mA) or shutdown mode (0.5 µA).

Key Specifications

Pinout & Package

FAQ

What is the maximum sampling rate of the MAX1188CCUP+T?

The MAX1188CCUP+T achieves a maximum sampling rate of 135 ksps under specified conditions (AVDD = DVDD = +5V ±5%, external reference). This allows accurate digitization of signals with fundamental frequencies up to ~67 kHz while maintaining full 16-bit resolution and AC performance metrics including –100 dB THD.

Does the MAX1188CCUP+T support ±10V analog input without external components?

Yes, the MAX1188CCUP+T natively supports a ±10V bipolar analog input range using its internal input scaler - no external op-amps, level shifters, or resistive dividers are required. The device maintains 16-bit monotonicity and ±2 LSB INL across the full range when operated with its internal +4.096V reference or an external 3.8–4.2V source.

How does the R/C pin control power modes in the MAX1188CCUP+T?

The R/C pin determines power state during the second falling edge of CS: low selects standby mode (reference and buffer remain active, 3.7 mA typical), enabling fast reacquisition; high selects shutdown mode (reference and buffer powered down, 0.5 µA typical), requiring 12 ms wake-up before next conversion. This dual-mode control optimizes power vs. latency trade-offs.

What package type and footprint does the MAX1188CCUP+T use?

The MAX1188CCUP+T uses a 20-pin TSSOP package (4.4 mm × 6.5 mm, 0.65 mm pitch) with exposed pad for thermal enhancement. It shares pin compatibility with other MAX1178/MAX1188 variants in the same family, allowing design reuse across ±5V and ±10V input versions without layout changes.

Can the MAX1188CCUP+T interface directly with 3.3V microcontrollers?

Yes, the MAX1188CCUP+T supports digital interface voltages from +2.7V to +5.25V on DVDD, enabling direct connection to 3.3V microcontrollers. Its VIH/VIL thresholds scale with DVDD (0.7× and 0.3× DVDD), and output drive strength meets 3.3V logic levels with VOH ≥ DVDD – 0.4V and VOL ≤ 0.4V at 1.6mA sink current.
