Product details
Overview
ICL7632CCJE from Maxim Integrated is a triple monolithic CMOS operational amplifier optimized for ultra-low input bias current (1 pA typical), programmable quiescent current (10 µA / 100 µA / 1 mA per amplifier), and rail-to-rail output swing - operating from ±1 V to ±8 V or 2 V to 16 V single supply. It features 16-pin CERDIP packaging, 0°C to +70°C temperature range, and is designed for high-impedance sensor interfacing in battery-powered pH meters and photodiode amplifiers.
For engineers reviewing the ICL7632CCJE datasheet, ICL7632CCJE pinout, ICL7632CCJE application, or ICL7632CCJE equivalent, key selection criteria include confirmed 1 pA input bias current, programmable IQ with corresponding GBW scaling (0.044–1.4 MHz), guaranteed common-mode voltage range (–0.4 V to +0.6 V), and verified 16-pin CERDIP mechanical compatibility with JEDEC MS-018.
Technical Context
The ICL7632CCJE implements a fully differential CMOS input stage with gate-isolated inputs enabling 10¹² Ω input resistance and 0.01 pA/√Hz input noise current. Its quiescent current is set via external voltage on dedicated IOC pins (Pin 2 and Pin 15), selecting 10 µA, 100 µA, or 1 mA per amplifier - directly scaling unity-gain bandwidth and slew rate while preserving rail-swing capability.
Unlike internally compensated variants, the ICL7632 is uncompensated and requires external gain-setting feedback networks; stability is guaranteed only at closed-loop gains ≥5 (IQ = 10 µA), ≥10 (IQ = 100 µA), or ≥20 (IQ = 1 mA). Output stage operates in Class A for linear swing into ≥1 MΩ loads, transitioning to Class AB for higher current drive into lower impedances.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Bias Current | 1 pA typical - enables stable DC coupling to >1 GΩ source impedances without significant offset drift. |
| Supply Voltage Range | ±1 V to ±8 V dual or 2 V to 16 V single - supports low-voltage portable instrumentation and wide-input industrial sensors. |
| Output Swing | ±4.9 V @ ±5 V supply, RL = 1 MΩ - delivers >98% rail-to-rail dynamic range for maximum signal fidelity. |
| Unity-Gain Bandwidth | 0.044 MHz (IQ = 10 µA) to 1.4 MHz (IQ = 1 mA) - scalable bandwidth allows power/performance trade-off per channel. |
| Input Resistance | 10¹² Ω - preserves signal integrity in high-Z applications like electrochemical sensors and piezoelectric transducers. |
| Common-Mode Voltage Range | –0.4 V to +0.6 V - ensures valid operation with inputs near supply rails, critical for single-supply signal conditioning. |
| Quiescent Current per Amp | Programmable: 10 µA / 100 µA / 1 mA - enables multi-tier power optimization across standby, active, and burst modes. |
Pinout & Package
ICL7632CCJE is housed in a 16-pin hermetically sealed CERDIP package (JEDEC MS-018), rated for 0°C to +70°C operation, with glass-sealed leads ensuring long-term reliability in humid or corrosive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | OUTA, OUTC | Amplifier A and C outputs - rail-swing CMOS outputs capable of sourcing/sinking current independent of IQ setting. |
| 2, 15 | IOC SET A, IOC SET C | Quiescent current control inputs - voltage level selects 10 µA (to V+), 100 µA (mid-rail), or 1 mA (to V−) per amplifier. |
| 3, 4 | +INA, –INA | Inverting/non-inverting inputs for Amp A - guarded layout required to preserve 1 pA bias spec; input impedance 10¹² Ω. |
| 5, 12 | N.C., IOB SET | No-connect (Pin 5); quiescent current control for Amp B (Pin 12) - matches Pin 2/15 functionality for third amplifier. |
| 6, 7, 8 | V+, –INB, +INC | Positive supply (6); Amp B inverting input (7); Amp C non-inverting input (8) - shared V+ powers all three amps. |
| 9, 10, 11 | +INB, –INC, –INB | Amp B non-inverting (9); Amp C inverting (10); Amp B inverting (11) - full differential input access per channel. |
| 13, 14 | OUTB, +INA | Amp B output (13); redundant +INA connection (14) - supports parallel input routing or layout flexibility. |
| V− (Pin 11 not used for V−) | Negative Supply | Applied externally to Pin 11 - note: Pin 11 is –INB; V− connects to Pin 11 only if using alternate pinout - per datasheet, V− is routed to Pin 11 in standard configuration per Figure 11. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-input-bias op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC1050CN#PBF | Single-channel, 1.5 pA max IB, fixed 125 µA IQ, 1.2 MHz GBW, 8-pin PDIP | Not pin-compatible; lacks programmable IQ and triple-channel integration | Select when single-channel operation suffices and higher GBW is needed at fixed power. |

FAQ
What is the input bias current specification for ICL7632CCJE?
The ICL7632CCJE has a typical input bias current of 1 pA at +25°C, with a maximum of 4 nA at +125°C. This ultra-low value is achieved through its CMOS input stage and enables direct interfacing with high-impedance sources such as pH electrodes and photodiodes without significant error. The ICL7632CCJE maintains this specification across its full operating temperature range of 0°C to +70°C.
How is quiescent current programmed on ICL7632CCJE?
Quiescent current on the ICL7632CCJE is programmed independently for each of its three amplifiers using dedicated IOC pins: Pin 2 (IOC SET A), Pin 12 (IOB SET), and Pin 15 (IOC SET C). Applying V+ selects 10 µA, connecting to mid-rail (V− + 0.8 V to V+ − 0.8 V) selects 100 µA, and tying to V− selects 1 mA. This allows per-channel optimization of bandwidth, slew rate, and power consumption in the ICL7632CCJE design.
Is ICL7632CCJE internally compensated?
No, the ICL7632CCJE is an uncompensated operational amplifier and requires external frequency compensation via feedback network design. Stability is guaranteed only at closed-loop gains ≥5 (with IQ = 10 µA), ≥10 (IQ = 100 µA), or ≥20 (IQ = 1 mA). Unlike the ICL7611/7621 series, the ICL7632CCJE does not include internal compensation capacitors - providing design flexibility for custom filter and integrator configurations.
What is the common-mode voltage range of ICL7632CCJE?
The ICL7632CCJE has a common-mode voltage range of –0.4 V to +0.6 V referenced to the supplies, applicable across all IQ settings. This range is narrower than extended-CMVR variants (e.g., ICL7612), but sufficient for most dual-supply sensor interfaces and single-supply applications where inputs remain within 0.6 V of either rail. The ICL7632CCJE does not support rail-to-rail input common-mode operation.
Which package type does ICL7632CCJE use?
The ICL7632CCJE uses a 16-pin CERDIP (Ceramic Dual In-line Package) with JEDEC MS-018 outline, featuring hermetically sealed ceramic construction and tin-lead leads. This package provides superior moisture resistance, thermal stability, and long-term parameter retention compared to plastic DIP - making it ideal for medical, test, and industrial applications where reliability is critical. The ICL7632CCJE's CERDIP package is distinct from plastic or SOIC variants in the same family.
