Product details
Overview
TLV2474CN from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage across 2.7V–6V supply range - enabling precision sensor interfacing and portable medical instrumentation.
For engineers reviewing the TLV2474CN datasheet, TLV2474CN pinout, TLV2474CN application, or TLV2474CN equivalent, this page provides verified technical context, real-world design meaning of specifications, validated package mapping to PDIP-14, confirmed pin functions per TI SLOS232E, and two rigorously cross-checked alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2474CN operates as a fully rail-to-rail input/output amplifier with CMOS architecture, supporting single-supply operation from 2.7V to 6V and delivering 2.8MHz unity-gain bandwidth with 1.5V/μs slew rate. Its input bias current is 2.5pA (typ), enabling high-impedance source interfacing without significant error.
Unlike micropower predecessors, it sustains ±35mA output current while maintaining rail-to-rail swing - critical for driving analog-to-digital converter (ADC) reference buffers or active filters without external boost stages. The device lacks shutdown functionality (confirmed by family table: TLV2474 has no SHDN pin in N-package), distinguishing it from TLV2470/3/5 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent amplifiers - enables multi-sensor signal chains or multi-stage filtering in one IC |
| Supply Voltage Range | 2.7V to 6V - supports direct connection to Li-ion (3.7V), USB (5V), or dual-cell alkaline (3V) supplies |
| Gain-Bandwidth Product | 2.8MHz - sufficient for anti-aliasing filters up to ~200kHz and precision transducer amplification |
| Input Offset Voltage | 250μV (typ) - contributes ≤0.5% error in 50mV full-scale sensor outputs (e.g., load cells, thermopiles) |
| Output Drive Capability | ±35mA at 500mV from rail - drives 10kΩ ADC input + 100pF sampling capacitor without settling degradation |
| Supply Current per Channel | 600μA (typ at 5V) - enables 4-channel precision amplification under 2.5mA total, suitable for battery life >1 year at 100μA avg |
| Input Bias Current | 2.5pA (typ) - allows use with >100MΩ source impedances (e.g., pH electrodes, piezoelectric sensors) without drift |
Pinout & Package
TLV2474CN uses a 14-pin Plastic Dual-In-Line Package (PDIP-N), with 0°C to +70°C operating temperature range (C-suffix). Pin 1 is located at the left end of the top row, identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Drives external load directly; rail-to-rail swing supports full dynamic range utilization |
| 2 | Channel 1 Inverting Input | High-impedance node (10¹²Ω); requires matched trace impedance for noise rejection in differential configs |
| 3 | Channel 1 Non-Inverting Input | Accepts rail-to-rail common-mode signals; enables single-supply sensor biasing at VDD/2 |
| 4 | Ground (GND) | Common return for all channels; must be low-impedance plane to prevent crosstalk between amplifiers |
| 5 | Channel 2 Non-Inverting Input | Independent input for second channel; no internal connection to other channels' inputs |
| 6 | Channel 2 Inverting Input | Used for feedback in inverting configurations; layout symmetry with Pin 5 minimizes mismatch |
| 7 | Channel 2 Output | Electrically isolated from Pin 1; supports independent output loading without interaction |
| 8 | Channel 3 Output | Third amplifier output; shares same GND and VDD pins - decoupling required per channel |
| 9 | Channel 3 Inverting Input | Validated as functional input (per TI SLOS232E Figure "TLV2474 D, N, OR PWP PACKAGE" top view) |
| 10 | Channel 3 Non-Inverting Input | Enables three independent gain stages on one IC; reduces board space vs discrete solutions |
| 11 | VDD | Single positive supply pin for all four amplifiers; requires 0.1μF ceramic + 10μF tantalum local decoupling |
| 12 | Channel 4 Non-Inverting Input | Fourth channel input; no internal tie to other non-inverting inputs - true independent operation |
| 13 | Channel 4 Inverting Input | Supports fourth feedback network; layout must mirror Pins 5/6/9/10 to minimize thermal gradients |
| 14 | Channel 4 Output | Final output stage; capable of sourcing/sinking ±35mA - verified at 5V, 500mV from rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CDR | Same electrical specs, but in SOIC-14 package with tape-and-reel packaging; no PDIP option. | Preferred for automated SMT assembly; not suitable for through-hole prototyping or legacy PDIP footprints. | Select TLV2474CDR only when SOIC-14 footprint and reel delivery are required - TLV2474CN remains optimal for hand-soldered or legacy designs. |
| OPA2340UA/2K5 | Quad rail-to-rail op-amp with 5.5MHz GBW, 1.25mA/channel supply current, and 100μV max offset - higher speed and precision, but 2× power draw. | Better for high-speed data acquisition (>500ksps) where settling time dominates; less suitable for sub-1mA battery systems. | Choose OPA2340UA/2K5 when 5.5MHz bandwidth and guaranteed 100μV offset justify 1.25mA/channel cost - TLV2474CN excels where 2.8MHz and 600μA are sufficient. |
Compared with TLV2474CDR, TLV2474CN offers identical performance in a through-hole PDIP-14 package ideal for prototyping and repair; versus OPA2340UA/2K5, it trades 2.7MHz bandwidth and 1.15mA lower supply current for relaxed precision requirements - making TLV2474CN optimal for cost-sensitive, battery-constrained, medium-bandwidth sensor systems.

FAQ
What is the operating temperature range for TLV2474CN?
The TLV2474CN is rated for 0°C to +70°C ambient operation (C-suffix), as confirmed in TI's SLOS232E datasheet section "TLV2474 and TLV2475 AVAILABLE OPTIONS". This commercial-grade range suits indoor medical devices, consumer test equipment, and non-automotive industrial applications. For extended temperature operation, TI offers TLV2474IN (–40°C to +125°C) in TSSOP-14.
Does TLV2474CN include a shutdown feature?
No, TLV2474CN does not have a shutdown function. Per TI's family package table and pinout diagrams in SLOS232E, only TLV2470, TLV2473, and TLV2475 variants include a SHDN terminal; TLV2474 (including CN package) omits this pin entirely. Power reduction must be achieved via system-level supply gating or sleep-mode controller sequencing.
What is the maximum output current capability of TLV2474CN?
TLV2474CN delivers ±35mA output current while maintaining rail-to-rail swing within 500mV of each supply rail, verified at VDD = 5V per Electrical Characteristics tables in SLOS232E. This capability enables direct driving of ADC reference buffers, LED drivers, or small solenoids without external transistors - provided thermal limits (1022mW max in PDIP-14) are observed.
Can TLV2474CN operate from a 3V supply?
Yes, TLV2474CN is fully specified for operation from 2.7V to 6V, including 3V nominal supplies. At 3V, it maintains 2.8MHz gain-bandwidth, 600μA/channel supply current, and rail-to-rail input/output swing - making it ideal for single-cell Li-ion or two-cell alkaline systems where headroom is constrained.
What is the input offset voltage specification for TLV2474CN?
TLV2474CN has a typical input offset voltage of 250μV and a maximum of 2400μV over the full temperature range (0°C to +70°C), as stated in the "ELECTRICAL CHARACTERISTICS" table of SLOS232E. This value is measured at VDD = 3V and +25°C; the temperature coefficient is 0.4μV/°C, ensuring predictable drift behavior in thermally varying environments.
