Product details
Overview
The MAX932CSA-TG069 from Maxim Integrated is a dual micropower comparator with integrated 1.182V ±2% bandgap reference, programmable hysteresis via HYST pin, TTL/CMOS-compatible outputs that source up to 40mA and sink ≥5mA, and operates from +2.5V to +11V single supply (or ±1.25V to ±5.5V dual supply). It targets battery-powered threshold detection and window comparator circuits where ultra-low quiescent current (<4µA over temperature) and rail-to-rail input range (V− to V+ −1.3V) are critical.
For engineers reviewing the MAX932CSA-TG069 datasheet, MAX932CSA-TG069 pinout, MAX932CSA-TG069 application, or MAX932CSA-TG069 equivalent, key selection criteria include its dual-comparator architecture with shared reference and hysteresis control, guaranteed operation across 0°C to +70°C, SO-8 package compatibility, and absence of crowbar current during output transitions-enabling stable performance in space-constrained, low-noise analog monitoring systems.
Technical Context
The MAX932CSA-TG069 integrates two independent comparators sharing a single internal 1.182V reference and one HYST pin for simultaneous hysteresis programming across both channels. Its input common-mode range extends from V− to (V+ −1.3V), supporting direct sensing near supply rails without level-shifting.
Each comparator features an output stage capable of continuous 40mA sourcing and >5mA sinking, with propagation delay of 12µs (10mV overdrive) and no switching crowbar current-eliminating supply-line glitches and parasitic feedback that compromise stability in poorly decoupled layouts.

| 4 INB− | Inverting input B | Second comparator's inverting input; identical electrical specs to INA−; supports differential or single-ended sensing |
| 5 INB+ | Noninverting input B | High-impedance input for comparator B; enables independent threshold setting vs. comparator A |
| 6 HYST | Hysteresis control | Accepts voltage from (REF −50mV) to REF; sets symmetrical hysteresis band via two external resistors |
| 7 REF | Internal reference output | 1.182V ±2% w.r.t. V−; sources ≤15µA/sinks ≥8µA; must not be bypassed |
| 8 V+ | Positive supply | Accepts +2.5V to +11V; powers comparators and reference; determines output swing ceiling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator with reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX932ESA | Same functionality and pinout; rated for −40°C to +85°C industrial temperature range | Required for outdoor or automotive-adjacent deployments where extended thermal margin is mandatory | Select MAX932ESA when operating ambient exceeds +70°C or requires MIL-STD reliability screening |
| MAX922CSA | 1% reference accuracy (vs. 2%), otherwise identical architecture and pinout; higher cost | Suitable for precision voltage monitoring where ±10mV trip-point error is unacceptable | Choose MAX922CSA only if reference drift must be halved-no benefit for general-purpose battery cutoff |
Compared with MAX932ESA and MAX922CSA, the MAX932CSA-TG069 offers optimal balance of cost, temperature rating, and reference tolerance for commercial portable electronics-delivering verified 2% reference stability and <4µA consumption without over-specifying for non-critical applications.

FAQ
What is the operating temperature range of the MAX932CSA-TG069?
The MAX932CSA-TG069 is specified for 0°C to +70°C operation. This commercial-grade temperature range aligns with consumer and industrial portable electronics where ambient conditions remain within controlled environments. The device's <4µA quiescent current and 1.182V ±2% reference are guaranteed across this full span, making it suitable for battery-powered medical monitors and handheld test tools without thermal derating.
Does the MAX932CSA-TG069 require external bypass capacitors?
No external bypass capacitors are required for the MAX932CSA-TG069 if the power supply impedance is low. However, a 100nF ceramic capacitor placed close to the V+ and V− pins is recommended when supply leads are long or source impedance is high. Critically, the REF pin must never be bypassed-doing so destabilizes the internal bandgap reference and degrades accuracy and noise performance.
Can the MAX932CSA-TG069 operate from a 3V supply?
Yes, the MAX932CSA-TG069 operates from +2.5V to +11V single supply, including 3V nominal systems. At 3V, supply current remains <4µA, propagation delay increases slightly to ~14µs (10mV overdrive), and output swing is reduced-but still sufficient for driving CMOS loads or LEDs with appropriate current limiting. Input common-mode range extends from V− to V+ −1.3V, supporting full 0–3V sensing.
How is hysteresis implemented on the MAX932CSA-TG069?
Hysteresis on the MAX932CSA-TG069 is implemented using the HYST pin: connect R1 between REF and HYST, and R2 between HYST and V−. This configuration applies identical hysteresis to both comparators. The hysteresis band (VHB) ≈ 2 × (VREF − VHYST), with VHYST adjustable from (REF −50mV) to REF-yielding up to 100mV total hysteresis. No external op-amps or feedback paths are needed.
Is the MAX932CSA-TG069 pin-compatible with other devices in the MAX93x family?
The MAX932CSA-TG069 shares the same 8-pin SO package and pinout as MAX932CUA, MAX932ESA, and MAX932CPA. It is not pin-compatible with MAX931, MAX933, or MAX934 due to differing channel counts and pin assignments. However, MAX932CSA-TG069 is functionally and physically interchangeable with all MAX932 variants in SO-8 packaging, enabling drop-in replacement across temperature grades.
